Rural-urban differences in health and health behaviour: a baseline description of a community health-promotion programme for the elderly

Using patterns of shared taxa to infer bacterial dispersal in human living environment in urban and rural areas

Contact with environmental microbial communities primes the human immune system. Factors determining the distribution of microorganisms, such as dispersal, are thus important for human health. Here, we used the relative number of bacteria shared between environmental and human samples as a measure of bacterial dispersal and studied these associations with living environment and lifestyles. We analyzed amplicon sequence variants (ASVs) of the V4 region of 16S rDNA gene from 347 samples of doormat dust as well as samples of saliva, skin swabs, and feces from 53 elderly people in urban and rural areas in Finland at three timepoints. We first enumerated the ASVs shared between doormat and one of the human sample types (i.e., saliva, skin swab, or feces) of each individual subject and calculated the shared ASVs as a proportion of all ASVs in the given sample type of that individual. We observed that the patterns for the proportions of shared ASVs differed among seasons and human sample type. In skin samples, there was a negative association between the proportion of shared ASVs and the coverage of built environment (a proxy for degree of urbanization), whereas in saliva data, this association was positive. We discuss these findings in the context of differing species pools in urban and rural environments.

IMPORTANCE

Understanding how environmental microorganisms reach and interact with humans is a key question when aiming to increase human contacts with natural microbiota. Few methods are suitable for studying microbial dispersal at relatively large spatial scales. Thus, we tested an indirect method and studied patterns of bacterial taxa that are shared between humans and their living environment.

Early-life circumstances and late life loneliness trajectories among Finnish older adults

BACKGROUND

Later life loneliness has become a significant public health concern worldwide. Research has focused on the prevalence, risk factors and consequences of loneliness in different age groups. This study aimed to advance the understanding of the impact of early-life circumstances on later life loneliness by examining the associations between adversities in childhood and youth and loneliness trajectories in Finnish older adults.

METHODS

The data were derived from the 10-year follow-up survey study Good Aging in the Lahti Region (n = 1552, mean age 64.89 years). The baseline study was conducted in 2002 with a regionally and locally stratified random sample of older persons living in the Lahti Region located in southern Finland. The follow-up surveys were carried out in 2005, 2008 and 2012. Loneliness was measured using a single question at the three follow-ups. Childhood conditions were retrospectively assessed at baseline with questions regarding the death of parents, household affection, relocation, and fear of a family member. Latent class growth analysis with time invariant covariates was used to identify loneliness trajectories and to examine the associations between loneliness trajectories and adverse circumstances in childhood and youth.

RESULTS

The results identified three distinct loneliness trajectories: low, moderate, and severe, including 36%, 50% and 14%, respectively, of the study population. The non-significant slopes of the three trajectories indicate that trajectories were stable during the seven years of follow-up. Being afraid of a family member, having a cold childhood, and death of a father or mother in childhood or youth significantly increased the odds of having a severe loneliness trajectory as compared to low loneliness trajectory. None of the early-life circumstances differentiated between severe and moderate levels of loneliness.

CONCLUSIONS

The findings suggest that some adverse early-life circumstances increase the odds of an unfavorable loneliness trajectory in later life. The results highlight the need to recognize the role of diverse life-course adversities in loneliness research and interventions. The study also underscores the importance of identifying individuals who are at risk of long-term and severe loneliness and providing them with appropriate support to decrease and/or prevent the negative health consequences of loneliness in old age.

Age-specific differences in the association between prediabetes and cardiovascular diseases in China: A national cross-sectional study

BACKGROUND

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide, the global burden of which is rising. It is still unclear the extent to which prediabetes contributes to the risk of CVD in various age brackets among adults. To develop a focused screening plan and treatment for Chinese adults with prediabetes, it is crucial to identify variations in the connection between prediabetes and the risk of CVD based on age.

AIM

To examine the clinical features of prediabetes and identify risk factors for CVD in different age groups in China.

METHODS

The cross-sectional study involved a total of 46239 participants from June 2007 through May 2008. A thorough evaluation was conducted. Individuals with prediabetes were categorized into two groups based on age. Chinese atherosclerotic CVD risk prediction model was employed to evaluate the risk of developing CVD over 10 years. Random forest was established in both age groups. SHapley Additive exPlanation method prioritized the importance of features from the perspective of assessment contribution.

RESULTS

In total, 6948 people were diagnosed with prediabetes in this study. In pre-diabetes, prevalences of CVD were 5 (0.29%) in the younger group and 148 (2.85%) in the older group. Overall, 11.11% of the younger group and 29.59% of the older group were intermediate/high-risk of CVD for prediabetes without CVD based on the Prediction for ASCVD Risk in China equation in ten years. In the younger age group, the 10-year risk of CVD was found to be more closely linked to family history of CVD rather than lifestyle, whereas in the older age group, resident status was more closely linked.

CONCLUSION

The susceptibility to CVD is age-specific in newly diagnosed prediabetes. It is necessary to develop targeted approaches for the prevention and management of CVD in adults across various age brackets.

Basic mobility, accidental falls, and lifetime physical activity among rural and urban community-dwelling older adults: a population-based study in Northern Iceland

The objective of this research was to investigate late-life physical functioning and lifetime history of physical activity (PA) among older adults in rural and urban Arctic communities. Data was collected in a cross-sectional, population-based study among 65 to 92-year-old community-dwelling Icelanders (N = 175, 41% ≥75-year-old, 43% women, 40% rural). Late-life physical functioning was operationalised as: basic mobility (Timed Up and Go in seconds, TUG); fall risk (TUG≥12 sec); a fall (≥1 fall/year); and recurrent falls (≥2 falls/year). PA history was based on a self-assessment. Compared to urban participants, rural participants were more likely to have fallen recently, be at fall risk, and describe more PA history. Among urban participants, no fall in the past year was independently associated with more PA in middle adulthood; and worse basic mobility and late-life fall risk were independently associated with being in the ≥75-year-old group. Among rural participants, recurrent falls were independently associated with being a man; and better basic mobility was independently associated with more PA in late adulthood. To conclude, this evidence supports an important association between better late-life physical functioning and more mid- and late-life PA and encourages further research to understand high fall risk among older men in Arctic rural areas.

Urban-Rural Differences in Mental and Physical Health among Primary Care Patients with Multiple Chronic Conditions: A Secondary Analysis from a Randomized Clinical Trial

PURPOSE

Rural health disparities are largely attributable to access to healthcare, socioeconomic status, and health behaviors. Little is known about the persistence of these disparities when differences in access to care are eliminated. We sought to investigate urban-rural differences in physical and mental health in primary care patients with demonstrated access to primary care.

METHODS

We obtained cross-sectional survey responses from a multicenter randomized controlled trial on 2726 adult primary care patients with multiple chronic medical or behavioral conditions from 42 primary care practices in 13 states. Study outcomes include measures of mental health including: The Patient-Reported Outcomes Measurement Information System (PROMIS-29®), General Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9), as well as physical health including: the PROMIS-29® and the Duke Activity Status Index (DASI). Urban-rural residence was indicated by census-tract Rural Urban Commuting Areas of the participant's home address. Differences in mental and physical health outcomes attributable to rurality were assessed using multilevel models with a random intercept for census-tract.

RESULTS

After adjustment for demographic and neighborhood characteristics, urban residents had significantly worse generalized anxiety disorder (GAD-7) (ß = 0.7; 95% CI = 0.1, 1.3; p = 0.027), depression (PHQ-9) (ß = 0.7; 95% CI = 0.1, 1.4; p = 0.024), and functional capacity (DASI) (ß = -0.4; 95% CI = -0.5, -0.2; p < 0.001) compared to rural residents. Urban residents also had significantly worse anxiety and depression as measured by the PROMIS-29® compared to their rural counterparts. There were no urban-rural differences in the other PROMIS-29® subdomains.

CONCLUSIONS

Among adults with demonstrated access to care and multiple diagnosed chronic conditions, rural residents had better mental health and functional capacity than their urban counterparts. This finding is not consistent with prior research documenting rural health disparities and should be confirmed.

Impact of a CBPR-informed physical activity intervention before and during COVID-19 among women from a disadvantaged neighborhood in Sweden

Background

Public health practitioners have been striving to reduce the social gradient and promote physical activity among citizens living in disadvantaged neighborhoods. The emergence of the COVID-19 pandemic, which has affected these citizens extensively, has posed a significant challenge to efforts to maintain a physically active lifestyle. Thus, the aim of this study was to explore the impact of a CBPR-informed physical activity intervention before and during the COVID-19 pandemic from the perspective of women from a socially disadvantaged neighborhood.

Methods

A total of 34 women participated in a CBPR-informed physical activity intervention previously developed in collaboration with lay health promoters and other citizens from the same neighborhood. Focus group discussions were conducted at four time points, namely, at baseline prior to the intervention, post-intervention, 6 months after the intervention ended, and during the COVID-19 pandemic. The data were analyzed using qualitative content analysis following an inductive approach.

Results

In total, four themes emerged from the discussions: "Wavering between frustration and action," "Shifting from prioritizing family needs to taking control of self," "Between isolation and social support," and "Restricted access to health-related knowledge vs. utilizing internalized knowledge".

Conclusion

The results of this study reveal that building on CBPR-informed health promotion initiatives has the potential to foster individual empowerment and assist during acute situations like the COVID-19 pandemic through mobilizing communities and their resources, which leads to increased community resilience and health. This study is regarded as unique in that it involves evaluation of a CBPR intervention that was initiated ahead of the pandemic and followed even during the pandemic.

Regional Variation in National Healthcare Expenditure and Health System Performance in Central Cities and Suburbs in Japan

The increasing national healthcare expenditure (NHE) with the aging rate is a significant social problem in Japan, and efficient distribution and use of NHE is an urgent issue. It is assumed that comparisons in subregions would be important to explore the regional variation in NHE and health system performance in targeted municipalities of the metropolitan area of Tokyo (central cities) and the neighboring municipalities of Chiba Prefecture (suburbs). This study aimed to clarify the differences of the socioeconomic factors affecting NHE and the health system performances between subregions. A multiple regression analysis was performed to extract the factors affecting the total medical expenses of NHE (Total), comprising the medical expenses of inpatients (MEI), medical expenses of outpatients (MEO), and consultation rates of inpatients (CRI) and outpatients (CRO). Using the stepwise method, dependent variables were selected from three categories: health service, socioeconomic, and lifestyle. Then, health system performance analysis was performed, and the differences between regions were clarified using the Mann–Whitney U test. The test was applied to 18 indicators, classified into five dimensions referred to in the OECD indicators: health status, risk factors for health, access to care, quality of care, and health system capacity and resources. In the central cities, the number of persons per household was the primary factor affecting Total, MEI, MEO, and CRO, and the number of persons per household and the percentage of the entirely unemployed persons primarily affected CRI. In the suburbs, the ratio of the population aged 65–74 and the number of hospital beds were significantly positively related to Total, MEI, and CRI, but the number of workers employed in primary industries was negatively related to Total and MEI. The ratio of the population aged 65–74 was significantly positively related to MEO and CRO. Regarding health system performance, while risk factors for health was high in the central cities, the others, including access to care, quality of care, and health system capacity and resources, were superior in the suburbs, suggesting that the health system might be well developed to compensate for the risks. In the suburbs, while risk factors for health were lower than those in the central cities, access to care, quality of care, and health system capacity and resources were also lower, suggesting that the healthcare system might be poorer. These results indicate a need to prioritize mitigating healthcare disparities in the central cities and promoting the health of the elderly in the suburbs by expanding the suburbs’ healthcare systems and resources. This study clarified that the determinants of NHE and health system performance are drastically varied among subregional levels and suggested the importance of precise regional moderation of the healthcare system.

Correlates of Positivity Among a Sample of Lebanese University Students

Background

People say it is hard to stay truly positive in Lebanon. Studies showed that 63% of Lebanese young adults are highly dissatisfied with their country. In fact, young adults are the most vulnerable population to stressors in Lebanon since their future is at stake and it is their time to shape their lives in a country that cripples them. This study aimed to assess factors (flourishing, religious coping, experiences in life, and the economic burden) associated with positivity among a sample of Lebanese university students despite the various stressors they are facing on top of the economic collapse and the COVID-19 pandemic.

Methods

This cross-sectional study was conducted between November and December 2021. A total of 333 participants (219 females and 114 males; mean age = 22.95 ± 4.79 years) was recruited through convenience sampling and snowball technique through several areas in Lebanon's governorates. A linear regression taking the positivity score as the dependent variable was adopted and all variables that showed a correlation > │0.24│ in absolute value were entered in the final model as independent.

Results

A linear regression taking the positivity score as the dependent variable showed that more positive experiences in life (Beta = 0.49; 95% CI 0.35-0.62), more flourishing (Beta = 0.10; 95% CI 0.05-0.14), living in rural area compared to urban (Beta = 3.06; 95% CI 2.02-4.11), and female gender (Beta = 1.56; 95% CI 0.50-2.61) were significantly associated with more positivity (Nagelkerke R ² of the model = 45.8%).

Conclusion

This study demonstrated that the youth's positivity is strongly affected by age, gender, residency, and the country they live in that will both directly and indirectly shape their life experiences and their ability to flourish and prosper. Along with all the efforts done to help during this collapse and alleviate the stress that young adults are enduring, follow-up studies are still needed to determine accurate coping techniques that pushes these young adults to think positively in a country where negativity reigns and all else fails.

Characterizing the Health of Older Rural Australians Attending Rural Events: Implications for Future Health Promotion Opportunities

This paper describes the health of older Australians (>65 years) attending rural events to inform health promotion interventions for rural populations. This cross-sectional study collected survey data and objective health measures between 2017 and 2020 at two events held in rural New South Wales, Australia. Participants included in the analysis were adults > 65 years of age. Data included demographic and health information, anthropometric measures (height, weight, waist circumference), and dietary and physical activity data. A total of 256 people > 65 years participated. Our sample, which was mostly male (59.0%), contained people aged between 66 and 75 years (72.3%). Participants lived in either a large rural (34.0%) or small rural town (22.3%), with low levels of education (60.9% did not complete high school). Dietary quality was rated as below average. All but 17.2% of the participants reported having a health condition. The risk of a health condition was associated with increasing age, lower education, and higher waist circumference, but not remoteness. Rural events may provide an opportunity to access, engage with, and understand the health of older rural Australians, especially males. They may offer ideal contexts for health and nutrition promotion opportunities in rural areas where access to health professionals is limited.

Association between health literacy and physical activity in older people: a systematic review and meta-analysis

Physical inactivity is common in older people and contributes to morbidity and mortality. Health literacy might play a role in motivating people to become or stay physically active. However, little is known about the influence of health literacy on physical activity in older people. This review aims to determine the association between health literacy and physical activity in older people. A systematic search was conducted in CINAHL, MEDLINE, PsychINFO and CENTRAL. Inclusion criteria: (i) community-dwelling people with an average age of ≥55 and (ii) reported on the association between health literacy and physical activity. Exclusion criteria: (i) population with a health condition and (ii) case study or qualitative study. Data were extracted independently by two reviewers. Risk of bias was assessed using the Downs and Black checklist. A meta-analysis was conducted using random-effects models with inverse variance. Thirteen articles were included in the review and five articles were selected for the meta-analysis. Older people with inadequate health literacy were 38% less likely than older people with adequate health literacy to report engaging in physical activity on ≥5 days per week [odds ratio = 0.62, 95% confidence interval (CI) 0.55-0.77]. Only two articles used activity monitors; the mean number of steps taken per day was not significantly different between older people with adequate and inadequate health literacy (standardized mean difference = -0.15, 95% CI -0.30 to 0.01). Physical activity could potentially be fostered by increasing health literacy and empowering older people to make beneficial health decisions.

Factors associated with health intentions and behaviour among health checkup participants in Japan

Health intentions and behaviours are essential for improving the health of individuals and society. This study used cross-sectional data from 20,155 health checkup participants in the Yamagata study to identify factors associated with health intentions and behaviours. Information regarding the current level of health intentions and behaviours was collected using a baseline survey questionnaire. Participants were categorised into three groups: having no intention (no intention), having intentions to improve but not acting on them (intention), and already active (action). The associations between background factors and the presence/absence of health intentions and behaviours were assessed using logistic regression analysis. Of the participants, 35.4%, 37.7%, and 26.9% belonged to the no intention, intention, and action groups, respectively. Multivariate analysis revealed that the factors associated with health intentions were being young, being female, longer duration of education, higher body mass index and abdominal circumference, diabetes, and dyslipidaemia. The factors associated with health behaviours were being older and male, not consuming alcohol, not smoking, performing daily exercise, and having diabetes. These results indicate that health guidance considering background factors, including age, gender, education, and comorbidities, may be useful for effectively promoting health intentions and health behaviours in the Japanese population.

Urban RCT participants were healthier than non-participants or rural women

OBJECTIVE

To investigate sociodemographic characteristics and physical and mental health indicators between participants and nonparticipants of a large-scale 2-year exercise RCT including noninvited women living in nearby rural area in Finland.

STUDY DESIGN AND SETTING

From a previous OSTPRE study cohort, 914 women (aged 72-84) participated in Kuopio Fall Prevention Study in 2016-2019. The participants were compared to non-participants (n = 4,536) and noninvited OSTPRE women (n = 7,119) living outside the urban recruitment area.

RESULTS

Participants were younger (P< 0.001) with higher education (P< 0.001) and had more often regular hobbies (P< 0.001) and physical exercising (P< 0.001) than nonparticipants or noninvited. They reported better functional capability (P< 0.001), mental (P< 0.001) and subjective health (P< 0.001), lower number of medications (P< 0.001), less fear of falls (P< 0.001), but more frequent falls (P= 0.002) and more often musculoskeletal diseases (P= 0.006).  Participants also showed better functional capacity in the clinical measurements. In register analysis, urban-rural differences in the prevalence of diseases were detected.

CONCLUSION

In population-based exercise interventions, participants are more likely to be better off in respect to physical and mental wellbeing, functional capability and sociodemographic status. Recruiting participants only from cities increases unavoidable selection bias due to urban-rural differences which should be noticed when interpreting and generalizing RCT results.

Health Disparities between the Rural and Urban Elderly in China: A Cross-Sectional Study

Background: China is becoming an aging society, and the proportion of the population aged 60 years and above is increasing. There is a dualistic urban–rural economic structure between urban and rural areas in China, but there are few comparative health studies on the self-assessed health (SAH) status of the elderly between urban and rural areas. The aim of this study is to explore the SAH status of the elderly in China, and to identify the health disparity between the urban and rural elderly. Methods: The data from the fourth wave of the China Health and Retirement Longitudinal Study (CHARLS) in 2018 were adopted. A total of 9630 participants aged 60 and above were included in this study. SAH was used as the indicator, measuring the health status. Fairlie decomposition analysis was conducted to find the SAH disparity. Results: The proportion of good SAH of the rural elderly (24.01%) was significantly higher than the urban elderly (19.99%). The association of SAH was widely different between the rural and urban elderly. There was a stronger association between SAH and sleeping time in the urban elderly (Odds ratios (OR) = 3.347 of 4–8 h; OR = 3.337 of above 8 h) than the rural elderly (OR = 1.630 of 4–8 h; OR = 2.293 of above 8 h). Smoking and social activity were significant only in the urban elderly, while region and assets were significant only in the rural elderly. Drinking (11.45%), region (−33.92%), and assets (73.50%) were the main factors contributing to the urban–rural health disparities. Conclusions: This is the first comparative study examining SAH disparity, focusing on the elderly aged 60 and above in China. From the perspective of drinking, region, and assets, our study highlighted substantial urban–rural health disparities, and provided evidence for policy making on narrowing the health gap between urban and rural areas in China.

The Health Status Transition and Medical Expenditure Evaluation of Elderly Population in China

(1) Background: Because of the rapid expansion of the aging population in China, their health status transition and future medical expenditure have received increasing attention. This paper analyzes the health transition of the elderly and how their health transition impacts medical expenditures. At the same time, feasible policy suggestions are provided to respond to the rising medical expenditure and the demand for social care. (2) Methods: The data were obtained from the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2015 and analyzed using the Markov model and the Two-Part model (TPM) to forecast the size of the elderly population and their medical expenditures for the period 2020-2060. (3) Results: The study indicates that: (1) for the elderly with a mild disability, the probability of their health improvement is high; in contrast, for the elderly with a moderate or severe disability, their health deterioration is almost certain; (2) the frequency of the diagnosis and treatments of the elderly is closely related to their health status and medical expenditure; alternatively, as the health status deteriorates, the intensity of the elderly individuals' acceptance of their diagnosis and treatment increases, and so does the medical expense; (3) the population of the elderly with mild and moderate disability demonstrates an inverted "U"-shape, which reaches a peak around 2048, whereas the elderly with severe disability show linear growth, being the target group for health care; (4) with the population increase of the elderly who have severe disability, the medical expenditure increases significantly and poses a huge threat to medical service supply. Conclusions: It is necessary to provide classified and targeted health care according to the health status of the elderly. In addition, improving the level of medical insurance, establishing a mechanism for sharing medical expenditure, and adjusting the basic demographic structure are all important policy choices.

Pain experience in an aging adult population during a 10-year follow-up

OBJECTIVES

This 10-year follow-up study aimed to examine the persistence of SF-36 pain intensity and pain-related interference and to identify baseline factors that may relate to pain experience among community-dwelling aging adults.

METHODS

Questionnaire and clinical data on a total of 1,954 participants (mean age at baseline 63 years) were collected in 2002, 2005, 2008, and 2012. Based on pain reports, four pain intensity, pain interference (PIPI) groups were formed at each time point: PIPI group I: none to mild pain intensity and interference; II: moderate to extreme pain intensity, none to mild pain-related interference; III: None to mild pain intensity, moderate to extreme pain-related interference, IV: Moderate to extreme pain intensity and interference.

RESULTS

Participants with the most pain at baseline improved their pain situation the most during the follow-up. Higher BMI was associated with pain interference, and metabolic syndrome (MetS) and musculoskeletal diseases with both pain intensity and interference (p<0.05, statistically significant interaction between pain intensity and pain interference) at baseline. According to multivariate logistic regression analysis the following baseline characteristics were associated with remaining in PIPI group I throughout the follow-up: presence of musculoskeletal disease (OR 0.22 [95% CI 0.16-0.30]), high BMI (OR 0.93 [95% CI 0.90-0.97]), high household income (OR 1.46 [95% CI 1.07-1.98]), good childhood home environment (OR 1.03 [95% CI 1.00-1.05]).

CONCLUSIONS

Multiple factors may affect pain persistence in late adulthood with varying effect on pain intensity and pain-related interference. Pain situation of even those with most pain may be improved.

Do Rural Second Homes Shape Commensal Microbiota of Urban Dwellers? A Pilot Study among Urban Elderly in Finland

According to the hygiene and biodiversity hypotheses, increased hygiene levels and reduced contact with biodiversity can partially explain the high prevalence of immune-mediated diseases in developed countries. A disturbed commensal microbiota, especially in the gut, has been linked to multiple immune-mediated diseases. Previous studies imply that gut microbiota composition is associated with the everyday living environment and can be modified by increasing direct physical exposure to biodiverse materials. In this pilot study, the effects of rural-second-home tourism were investigated on the gut microbiota for the first time. Rural-second-home tourism, a popular form of outdoor recreation in Northern Europe, North America, and Russia, has the potential to alter the human microbiota by increasing exposure to nature and environmental microbes. The hypotheses were that the use of rural second homes is associated with differences in the gut microbiota and that the microbiota related to health benefits are more diverse or common among the rural-second-home users. Based on 16S rRNA Illumina MiSeq sequencing of stool samples from 10 urban elderly having access and 15 lacking access to a rural second home, the first hypothesis was supported: the use of rural second homes was found to be associated with lower gut microbiota diversity and RIG-I-like receptor signaling pathway levels. The second hypothesis was not supported: health-related microbiota were not more diverse or common among the second-home users. The current study encourages further research on the possible health outcomes or causes of the observed microbiological differences. Activities and diet during second-home visits, standard of equipment, surrounding environment, and length of the visits are all postulated to play a role in determining the effects of rural-second-home tourism on the gut microbiota.

Urban-rural differences in overweight and obesity among 25-64 years old Myanmar residents: a cross-sectional, nationwide survey

OBJECTIVES

To investigate whether urban-rural location and socioeconomic factors (income, education and employment) are associated with body mass index (BMI) and waist-hip ratio (W/H-ratio), and to further explore if the associations between urban-rural location and BMI or W/H-ratio could be mediated through variations in socioeconomic factors.

DESIGN

Cross-sectional, WHO STEPS survey of non-communicable disease risk factors.

SETTING

Urban and rural areas of Myanmar.

PARTICIPANTS

A total of 8390 men and women aged 25 to 64 years included during the study period from September to December 2014. Institutionalised people (Buddhist monks and nuns, hospitalised patients) and temporary residents were excluded.

RESULTS

The prevalence of overweight and obesity was higher in the urban areas and increased with increasing socioeconomic status (SES) score. Mean BMI was higher among urban residents (ß=2.49 kg/m²; 95% CI 2.28 to 2.70; p<0.001), individuals living above poverty line, that is, ≥US$1.9/day (ß=0.74 kg/m²; 95% CI 0.43 to 1.05; p<0.001), and those with high education attainment (ß=1.48 kg/m²; 95% CI 1.13 to 1.82; p<0.001) when adjusting for potential confounders. Similarly, greater W/H-ratio was observed in participants living in an urban area, among those with earnings above poverty line, and among unemployed individuals. The association between urban-rural location and BMI was found to be partially mediated by a composite SES score (9%), income (17%), education (16%) and employment (16%), while the association between urban-rural location and W/H-ratio was found to be partially mediated by income (12%), education (6%) and employment (6%).

CONCLUSION

Residents living in urban locations had higher BMI and greater W/H-ratio, partially explained by differences in socioeconomic indicators, indicating that socioeconomic factors should be emphasised in the management of overweight and obesity in the Myanmar population. Furthermore, new national or subnational STEPS surveys should be conducted in Myanmar to observe the disparity in trends of the urban-rural differential.

Associations between land cover categories, gaseous PAH levels in ambient air and endocrine signaling predicted from gut bacterial metagenome of the elderly

There is evidence that polycyclic aromatic hydrocarbons (PAHs) and human gut microbiota are associated with the modulation of endocrine signaling pathways. Independently, studies have found associations between air pollution, land cover and commensal microbiota. We are the first to estimate the interaction between land cover categories associated with air pollution or purification, PAH levels and endocrine signaling predicted from gut metagenome among urban and rural populations. The study participants were elderly people (65-79 years); 30 lived in rural and 32 in urban areas. Semi-Permeable Membrane devices were utilized to measure air PAH concentrations as they simulate the process of bioconcentration in the fatty tissues. Land cover categories were estimated using CORINE database and geographic information system. Functional orthologues for peroxisome proliferator-activated receptor (PPAR) pathway in endocrine system were analyzed from gut bacterial metagenome with Kyoto Encyclopaedia of Genes and Genomes. High coverage of broad-leaved and mixed forests around the homes were associated with decreased PAH levels in ambient air, while gut functional orthologues for PPAR pathway increased along with these forest types. The difference between urban and rural PAH concentrations was not notable. However, some rural measurements were higher than the urban average, which was due to the use of heavy equipment on active farms. The provision of air purification by forests might be an important determining factor in the context of endocrine disruption potential of PAHs. Particularly broad-leaved forests around homes may reduce PAH levels in ambient air and balance pollution-induced disturbances within commensal gut microbiota.

Analgesic purchases among older adults - a population-based study

Background

Pain is a frequent and inevitable factor affecting the quality of life among older people. Several studies have highlighted the ineffectiveness of treating chronic pain among the aged population, and little is known about the prevalence of analgesics administration among community-dwelling older adults. The objective was to examine older adults’ prescription analgesic purchases in relation to SF-36 pain in a population-based setting.

Methods

One thousand four hundred twenty community-dwelling citizens aged 62–86 years self-reported SF-36 bodily pain (pain intensity and pain-related interference) scores for the previous 4 weeks. The Social Insurance Institution of Finland register data on analgesic purchases for 6 months prior to and 6 months after the questionnaire data collection were considered. Special interest was focused on factors related to opioid purchases.

Results

Of all participants, 84% had purchased prescription analgesics during 1 year. NSAIDs were most frequently purchased (77%), while 41% had purchased paracetamol, 32% opioids, 17% gabapentinoids, and 7% tricyclic antidepressants. Age made no marked difference in purchasing prevalence. The number of morbidities was independently associated with analgesic purchases in all subjects and metabolic syndrome also with opioid purchases in subjects who had not reported any pain.

Discussion

Substantial NSAID and opioid purchases emerged. The importance of proper pain assessment and individual deliberation in terms of analgesic contraindications and pain quality, as well as non-pharmacological pain management, need to be highlighted in order to optimize older adults’ pain management.

Understanding coastal public health: Employment, behavioural and psychosocial factors associated with geographical inequalities. The HUNT study, Norway

Recent decades have shown an international trend of decline in small-scale fishing; a longstanding and vital industry for numerous coastal populations. The decline has resulted in a loss of livelihoods in many coastal communities, potentially afflicting public health. Still, knowledge about the health situation of these areas is limited. Former studies on coastal health have primarily defined coastal areas based solely on their proximity to the coast, therefore not targeting the traditional coastal communities with longstanding coastal involvement through small-scale fishing. In this paper, we aim to illuminate the health situation in these areas by introducing a more fine-grained classification of the coastal study population; considering both geographical proximity to the coast, population density and employment in fishing. Using data from the Norwegian population-based HUNT Study, we perform individual and simultaneous adjustments for employment, behavioural and psychosocial factors to assess the contributions of these factors to the association between geographical affiliation and self-rated general health. The rural coastal areas with a history of small-scale fishing show a poorer health situation compared to urban coastal, rural inland and rural fjord populations, and behavioural factors contribute the most to the observed health disparities. Our findings encourage greater focus on societal differences between coastal communities when studying coastal health.

Yard vegetation is associated with gut microbiota composition

Gut microbes play an essential role in the development and functioning of the human immune system. A disturbed gut microbiota composition is often associated with a number of health disorders including immune-mediated diseases. Differences in host characteristics such as ethnicity, living habit and diet have been used to explain differences in the gut microbiota composition in inter-continental comparison studies. As our previous studies imply that daily skin contact with organic gardening materials modify gut microflora, here we investigated the association between living environment and gut microbiota in a homogenous western population along an urban-rural gradient. We obtained stool samples from 48 native elderly Finns in province Häme in August and November 2015 and identified the bacterial phylotypes using 16S rRNA Illumina MiSeq sequencing. We assumed that yard vegetation and land cover classes surrounding homes explain the stool bacterial community in generalized linear mixed models. Diverse yard vegetation was associated with a reduced abundance of Clostridium sensu stricto and an increased abundance of Faecalibacterium and Prevotellaceae. The abundance of Bacteroides was positively and strongly associated with the built environment. Exclusion of animal owners did not alter the main associations. These results suggest that diverse vegetation around homes is associated with health-related changes in gut microbiota composition. Manipulation of the garden diversity, possibly jointly with urban planning, is a promising candidate for future intervention studies that aim to maintain gut homeostasis.

All-cause mortality rate in China: do residents in economically developed regions have better health?

Background

Urban-rural disparities have been extensively investigated, while most investigators overlooked urban-suburban-rural variations in population health. Although regional disparities in East-West China have been largely discussed, limited attention has been directed to the interaction between regional differences and urban-suburban-rural disparities. This study aims to analyze urban-suburban-rural variations in all-cause mortality rates across four geographic regions in China.

Methods

Data came from China’s National Census Survey and public statistical yearbooks in 2000 and 2010. Urban districts, county-level cities, and counties were respectively defined as urban, suburban, and rural areas. We obtained 2322 areas, including 2148 areas with two observations and 174 areas with only one observation. Data visualization was performed to depict geographic variations and changes in all-cause mortality rates. Five hierarchical linear regression analyses with generalized estimating equations (GEE) were employed to analyze variations in all-cause mortality rates over time. Demographic and socioeconomic attributes were introduced as covariates.

Results

Despite an overall decline in all-cause mortality rate, rural residents generally achieved worse health than urban and suburban counterparts. In contrast, urban-suburban disparities could be fully explained by demographic and socioeconomic differences. In addition, Northeastern and Central residents achieved better health than Eastern and Western residents. Last, there existed urban/suburban-rural disparities in all regions, except Northeastern, where urban/suburban-rural disparities were eliminated after controlling for socioeconomic and demographic attributes.

Conclusion

Even though suburban and rural areas were often merged, there exist urban/suburban-rural disparities in population health. Furthermore, urban/suburban-rural disparities vary across regions.

CVD risk factors and surrogate markers - Urban-rural differences

Aims: Disparity in cardiovascular disease (CVD) mortality and risk factor levels between urban and rural regions has been confirmed worldwide. The aim of this study was to examine how living in different community types (urban-rural) in childhood and adulthood are related to cardiovascular risk factors and surrogate markers of CVD such as carotid intima-media thickness (IMT) and left ventricular mass (LVM). Methods: The study population comprised 2903 participants (54.1% female, mean age 10.5 years in 1980) of the Cardiovascular Risk in Young Finns Study who had been clinically examined in 1980 (age 3-18 years) and had participated in at least one adult follow-up (2001-2011). Results: In adulthood, urban residents had lower systolic blood pressure (-1 mmHg), LDL-cholesterol (-0.05 mmol/l), lower body mass index (-1.0 kg/m²) and glycosylated haemoglobin levels (-0.05 mmol/mol), and lower prevalence of metabolic syndrome (19.9 v. 23.7%) than their rural counterparts. In addition, participants continuously living in urban areas had significantly lower IMT (-0.01 mm), LVM (1.59 g/m^2.7) and pulse wave velocity (-0.22 m/s) and higher carotid artery compliance (0.07%/10 mmHg) compared to persistently rural residents. The differences in surrogate markers of CVD were only partially attenuated when adjusted for cardiovascular risk factors. Conclusions: Participants living in urban communities had a more favourable cardiovascular risk factor profile than rural residents. Furthermore, participants continuously living in urban areas had less subclinical markers related to CVD compared with participants living in rural areas. Urban-rural differences in cardiovascular health might provide important opportunities for optimizing prevention by targeting areas of highest need.

Pain-related factors in older adults

BACKGROUND AND AIMS

Pain is an evident factor affecting the quality of life in all age groups. The objective was to examine the prevalence of self-reported SF-36 bodily pain and pain-related factors in community-dwelling older adults.

METHODS

One thousand four hundred and twenty adults aged 62-86 years self-reported SF-36 bodily pain during the previous month. For the analysis, four pain groups were formed (group I [0-45, moderate to very severe pain intensity and interference], group II [47.5-70], group III [77.5-90], and group IV [100, no pain at all]). Additional questionnaire-provided data regarding education, wealth, life habits, and morbidity, as well as clinical data were considered.

RESULTS

The overall pain prevalence was 78% (SF-36 bodily pain score <100). The prevalence of cohabiting, as well as the years of education and household income were found to decrease with an increasing SF-36 bodily pain score. The prevalence of a BMI of over 30 and of central obesity emerged as the highest in group I. Morbidities were found to be most prevalent in group I.

CONCLUSIONS

A high prevalence of intense and interfering pain was reported. Multiple factors that were found to relate to pain have previously been demonstrated to associate with social exclusion. Increasing attention should be paid to distinguishing these factors in patients with pain, as well as targeted pain assessment and measures to improve the sense of community among older adults.

IMPLICATIONS

There is a lack of large studies that examine a wide scale of pain-related factors in the older adult population. To distinguish subjects with multiple such factors would help medical professionals to target their attention to patients at a high risk of chronic pain.

Regional differences in morbidity profiles and health care use in the oldest old: Findings from two Centenarian Studies in Portugal

BACKGROUND

The worldwide increase of human life expectancy and the rapid aging of the population will contribute to an increasing prevalence of chronic illness. Even so, individuals who reach very advanced ages often postpone or escape age-related diseases that are common causes of death.

OBJECTIVE

This article aims to examine health-related characteristics of two distinct samples of Portuguese centenarians (one predominantly rural - PR vs. one predominantly urban - PU), and explore potential dissimilarities in their morbidity profiles and use of health care services.

METHODS

A total of 241 centenarians were considered. Sociodemographic characteristics, health status, and use of health care services were assessed by semi-structured interviews with the centenarians and their proxies (family or formal caregiver).

RESULTS

A higher average of 4.80 self-reported illnesses (sd = 2.01) were found in the PU sample (vs. 2.96; sd = 1.77 in the PR sample); in overall the PR sample presented a better health condition with lower levels of physical and mental impairments, and a greater number of centenarians who did not succumb to the three most common lethal diseases (heart disease, non-skin cancer and stroke) in the elderly population (85.4% vs. 60% in the PU sample).

CONCLUSIONS

Portuguese centenarians experienced a substantial number of illnesses, but an overall better health status was found in centenarians from the PR area. By providing distinctive health-related profiles, our findings suggest the importance of contextual factors in shaping how very advanced ages may be achieved.

Socioeconomic transition and its influence on body mass index (BMI) pattern in Bangladesh

RATIONALE, AIMS, AND OBJECTIVES

Bangladesh is an underdeveloped country that has recently joined the ranks of low-middle-income countries. This study aims to investigate how socioeconomic and developmental factors have influenced women towards a shift in their body mass index (BMI).

METHODS

The trend was analysed using data on ever-married women from 6 nationwide surveys covering the years 1996 to 2014, conducted by the Bangladesh Demographic and Health Survey (BDHS). To assess the relationship between the socioeconomic factors and BMI, binary regression models were fitted for 6 surveys and forest plots were applied to display the results.

RESULTS

Factors such as age, education, residence, economic status, and contraceptive use were found to have had an increasing influence on BMI over the years that were being analysed. Age and education for women were potential factors influencing BMI. Growing urbanization and economic inequality were found to have been substantial over time, and marital status and contraceptive use were influential whilst the employment status of women held no consequence.

CONCLUSIONS

Rapid urbanization allied with growing wealth inequality and dietary alteration seems to have forced a change in the capacity of women in Bangladesh to control their weight. Additional information is still needed on such factors as the amount of time that women are inactive and sitting down, for example, as well as their daily calorie intake in order to assemble all the pieces for addressing necessary health policy changes in Bangladesh. These factors will also help to indicate a shift of focus from rural malnutrition to urban obesity.

Relationships Between Neighbourhood Physical Environmental Attributes and Older Adults' Leisure-Time Physical Activity: A Systematic Review and Meta-Analysis

BACKGROUND

Activity-friendly neighbourhood physical environments with access to recreational facilities are hypothesised to facilitate leisure-time physical activity (LTPA) among older adults (≥ 65 years old). The aim of the current study was to systematically review and quantitatively summarise study findings on the relationships between physical environmental attributes and LTPA among older adults.

METHODS

An extensive search of literature, including grey literature, yielded 72 articles eligible for inclusion. The reported associations between seven categories of environmental attributes and six LTPA outcomes were extracted, weighted by sample size and study quality, and quantitatively summarised. Reported moderating effects of individual and environmental characteristics and neighbourhood definition were also examined.

RESULTS

We observed positive associations for walkability (p = 0.01), land-use mix-access (p = 0.02) and aesthetically pleasing scenery (p < 0.001) with leisure-time walking. For leisure-time walking within the neighbourhood, evidence was found for positive associations with land-use mix-access (p = 0.03) and access to public transit (p = 0.05), and a negative association with barriers to walking/cycling (p = 0.03). Evidence for positive relationships between overall LTPA and access to recreational facilities (p = 0.01) and parks/open space (p = 0.04) was found. Several environmental attribute-LTPA outcome combinations were insufficiently studied to draw conclusions. No consistent moderating effects were observed for individual and environmental characteristics and neighbourhood definition.

CONCLUSIONS

The observed significant relationships can be used to inform policy makers and planners on how to (re-)design neighbourhoods that promote LTPA among older adults. Many environmental attribute-LTPA outcome relationships have been studied insufficiently and several methodological issues remain to be addressed.

Urbanization Reduces Transfer of Diverse Environmental Microbiota Indoors

Expanding urbanization is a major factor behind rapidly declining biodiversity. It has been proposed that in urbanized societies, the rarity of contact with diverse environmental microbiota negatively impacts immune function and ultimately increases the risk for allergies and other immune-mediated disorders. Surprisingly, the basic assumption that urbanization reduces exposure to environmental microbiota and its transfer indoors has rarely been examined. We investigated if the land use type around Finnish homes affects the diversity, richness, and abundance of bacterial communities indoors. Debris deposited on standardized doormats was collected in 30 rural and 26 urban households in and near the city of Lahti, Finland, in August 2015. Debris was weighed, bacterial community composition determined by high throughput sequencing of bacterial 16S ribosomal RNA (rRNA) gene on the Illumina MiSeq platform, and the percentage of four different land use types (i.e., built area, forest, transitional, and open area) within 200 m and 2000 m radiuses from each household was characterized. The quantity of doormat debris was inversely correlated with coverage of built area. The diversity of total bacterial, Proteobacterial, Actinobacterial, Bacteroidetes, and Firmicutes communities decreased as the percentage of built area increased. Their richness followed the same pattern except for Firmicutes for which no association was observed. The relative abundance of Proteobacteria and particularly Gammaproteobacteria increased, whereas that of Actinobacteria decreased with increasing built area. Neither Phylum Firmicutes nor Bacteroidetes varied with coverage of built area. Additionally, the relative abundance of potentially pathogenic bacterial families and genera increased as the percentage of built area increased. Interestingly, having domestic animals (including pets) only altered the association between the richness of Gammaproteobacteria and diversity of Firmicutes with the built area coverage suggesting that animal ownership minimally affects transfer of environmental microbiota indoors from the living environment. These results support the hypothesis that people living in densely built areas are less exposed to diverse environmental microbiota than people living in more sparsely built areas.

Association among activities of daily living, instrumental activities of daily living and health-related quality of life in elderly Yi ethnic minority

Background

The health-related quality of life (HRQoL) of the elderly population of Yi ethnic minority, which is the seventh largest nationality in China, has been rarely reported. This study was designed to explore the HRQoL of the elderly Yi ethnicity and association between their HRQOL and functional abilities.

Methods

A total of 291 Yi ethnic residents were randomly recruited from 12 rural counties in Yunnan province and divided into different age groups. Local residents in Yunnan province and the elderly from Hangzhou were enrolled as controls. The MOS 36-Item Short Form Health Survey (SF-36), activities of daily living (ADL), instrumental activities of daily living (IADL) scales were utilized to evaluate the HRQoL and functional ability. One-way ANOVA was used to statistically compare the ADL and IADL among different age groups. The influential variables on HRQOL were analyzed by multiple linear regression analysis. Pearson correlation analysis was used to analyze the association among HRQoL, ADL and IADL.

Results

The HRQoL of the elderly Yi minority was significantly lower than those of local residents in Yunnan province and the elderly counterparts in Hangzhou. The IADL ability of the elderly Yi minority was low, whereas they could perform most items of ADL. ADL, IADL, and education level were positively associated with HRQoL, whereas age, chronic diseases, and the frequency of medication use were negatively correlated with HRQoL.

Conclusion

The HRQoL and functional capacity of the elderly Yi ethnic minority were lower compared with their counterparts in Yunnan province and Hangzhou. The low level of IADL indicated that the elderly Yi participants had a high risk of cognitive impairment. Much attention should be diverted to influential factors of the HRQoL.

Acceptability of HIV Testing Sites Among Rural and Urban African Americans Who Use Cocaine

African Americans (AAs) who use cocaine in the Southern region of the U.S. have a relatively high risk of HIV and need for HIV testing. Among this group, those residing in rural areas may have less favorable opinions about common HIV testing sites, which could inhibit HIV testing. We examined rural/urban variations in their acceptability of multiple HIV testing sites (private physician clinic, local health department, community health center, community HIV fair, hospital emergency department, blood plasma donation center, drug abuse treatment facility, and mobile van or community outreach worker). Results from partial proportional odds and logistic regression analyses indicate that rural AA who use cocaine have lower odds of viewing local health departments (OR = 0.09, 95 % CI = 0.03-0.21), physician offices (OR = 0.19, 95 % CI = 0.09-0.42), and drug use treatment centers (OR = 0.49; 95 % CI = 0.30-0.80) as acceptable relative to their urban counterparts. The findings have implications for further targeting HIV testing toward AAs who use of cocaine, particularly those residing in the rural South.

Coping: Impact of Gender and Stressful Life Events in Middle and in Old Age

OBJECTIVES

This study seeks to identify different life events that participants considered stressful and to study the joint effect of gender, age group, and main stressful life events on the use of different coping strategies.

METHODS

The sample comprised 243 men and women, 55 to 99 years old, who attended senior activity centers. Analyses were conducted using multivariate analysis of variance (MANOVA).

RESULTS

Three main categories of stressful life events were identified: health problems, family problems, and other problems. Significant main effects of gender and stressful life events, and marginal effects of age group on coping strategies were found. Furthermore, an interaction between gender and age group, and also between gender and stressful life events emerged in some of the coping strategies analyzed.

CONCLUSIONS

Age, gender or type of stressful situation impact on the coping strategies used by older people. Older men and women were found to use different strategies depending upon the situation they are facing and upon their age group. The results may prove useful to practitioners and clinicians who directly work with older people and may help clinicians provide effective coping strategies to address the specific life events that older adults find stressful.

Risk Factors for Six Types of Disability among the Older People in Thailand in 2002, 2007, and 2011

Background. There is an important need to characterize risk factors for disability in Thailand, in order to inform effective prevention and control strategies. This study investigated factors associated with risk of 6 types of disability in Thailand's ageing population in 2002, 2007, and 2011. Methods. Data came from the Cross-Sectional National Surveys of Older Persons in Thailand conducted by the National Statistical Office (NSO) in 2002, 2007, and 2011. Stratified two-stage sampling was employed. Interviews of 24,835, 30,427, and 34,173 elderly people aged 60 and above were conducted in the respective study years. Prevalence of disabilities was measured, and factors associated with disability risk were assessed with probability-weighted multiple logistic regression. Results. Disability prevalence decreased slightly over the study period. The characteristics with greatest positive impact on disability prevalence were not working over the past week (average impact: 61.2%), age (53.7% per decade), and suffering from one or more chronic illnesses (46.3%). Conclusions. The strong observed positive impact of not working on disability prevalence suggests that raising the mandatory retirement age might result in some reduction of disability risk. Also, the observed positive impact of living with others (versus alone) on disability risk was somewhat unexpected.

Neighbourhood effects in health behaviours: a test of social causation with repeat-measurement longitudinal data

BACKGROUND

Neighbourhood characteristics have been associated with health behaviours of residents. We used longitudinal data to examine whether neighbourhood characteristics (level of urbanization and socioeconomic status) are related to within-individual variations in health behaviours (alcohol consumption, smoking, exercise and self-interest in health) as people live in different neighbourhoods over time.

METHODS

Participants were from the Young Finns prospective cohort study (N = 3145) with four repeated measurement times (1992, 2001, 2007 and 2011/2012). Neighbourhood socioeconomic status and level of urbanization were measured on the level of municipality and zip code area. Within-individual (i.e. fixed-effect) regression was used to examine whether these associations were observed within individuals who lived in different neighbourhood in different measurement times.

RESULTS

People living in more urban zip code areas were more likely to smoke (b = 0.06; CI = 0.03-0.09) and drink alcohol (b = 0.11; CI = 0.08-0.14), and these associations were replicated in within-individual analysis-supporting social causation. Neighbourhood socioeconomic status and urbanization were associated with higher interest in maintaining personal health (b = 0.05; CI = 0.03-0.08 and b = 0.05; CI = 0.02-0.07, respectively), and these associations were also similar in within-individual analysis. Physical exercise was not associated with neighbourhood characteristics.

CONCLUSIONS

These data lend partial support for the hypothesis that neighbourhood differences influence people's health behaviours.

Conceptual and operational considerations in identifying socioenvironmental factors associated with disability among community-dwelling adults

Disability is conceived as a person–context interaction. Physical and social environments are identified as intervention targets for improving social participation and independence. In comparison to the body of research on place and health, relatively few reports have been published on residential environments and disability in the health sciences literature. We reviewed studies evaluating the socioenvironmental correlates of disability. Searches were conducted in Medline, Embase and CINAHL databases for peer-reviewed articles published between 1997 and 2014. We found many environmental factors to be associated with disability, particularly area-level socioeconomic status and rurality. However, diversity in conceptual and methodological approaches to such research yields a limited basis for comparing studies. Conceptual inconsistencies in operational measures of disability and conceptual disagreement between studies potentially affect understanding of socioenvironmental influences. Similarly, greater precision in socioenvironmental measures and in study designs are likely to improve inference. Consistent and generalisable support for socioenvironmental influences on disability in the general adult population is scarce.

Does residing in urban or rural areas affect the incidence of polypharmacy among older adults in western China?

The aim of this study is to explore the differences among older adults who are rural or urban residents with respects to their socioeconomic position, chronic health conditions and medication use. This cross-sectional study included 887 community-dwelling older adults (≥60 years) from western China. Trained interviewers collected data from all of the study subjects through face-to-face interviews. Polypharmacy was defined as the concomitant use of five or more medications. A total of 717 participants were included in the study analyses. Compared with their urban counterparts, the older adults in rural China were more likely to have more chronic health conditions, and a lower education level, annual income and insurance coverage rate. In addition, the rural inhabitants were less likely to use medications (58.7% vs. 75.7%, p<0.001). The intensity of medication use (the mean number of drugs) was 1.7 for rural residents and 2.3 for urban residents (p<0.001). The prevalence of polypharmacy was significantly lower in rural residents than urban residents (11.5% vs. 17.5%, p=0.021). Urban residence (odds ratios (OR) 1.89, 95% confidence intervals (CI) 1.03-3.48), number of chronic conditions (OR 1.95, 95% CI 1.16-3.30), diabetes (OR 4.14, 95% CI 2.33-7.37), and cardiovascular disease (CVD) (OR 2.09, 95% CI 1.25-3.51) were positively associated with polypharmacy, whereas good self-rated health (OR 0.32, 95% CI 0.16-0.65) was negatively associated with polypharmacy. In conclusion, urban residence is independently associated with polypharmacy in Chinese elders regardless of chronic health conditions and socioeconomic status.

Nutritional status and its health-related factors among older adults in rural and urban areas

AIM

To compare health-related characteristics, nutrition-related factors and nutritional status of older adults living in rural and urban counties of Taiwan.

BACKGROUND

The older adult population of Taiwan is increasing. Furthermore, older people living in rural areas have shorter life expectancy and more chronic diseases than their urban counterparts. However, little is known about the health-related characteristics, nutrition-related factors and nutritional status of older adults living in rural and urban areas of Taiwan, limiting nurses' ability to identify and care for older adults at risk of poor nutritional health.

DESIGN

Cross-sectional, comparative.

METHODS

Older adults were randomly selected from names of residents of an adjacent rural and urban area of northern Taiwan and having completing the 2009 health evaluation. From March-July 2010, older adult participants (N = 366) provided data on demographic and health-related information, nutritional self-efficacy, health locus of control and nutritional status. Data were analysed by descriptive statistics and compared using chi-square and t-test.

RESULTS

Older rural participants had significantly lower educational level, less adequate income, higher medication use, lower scores on self-rated health status and researcher-rated health status and lower self-rated healthy eating status than their urban counterparts. Moreover, rural participants had significantly lower nutritional self-efficacy, higher chance health locus of control and poorer nutritional status than their urban counterparts.

CONCLUSIONS

Our results suggest that nurses should assess older adults living in rural areas for nutritional health and nutrition knowledge. Based on this assessment, nurses should develop easy, practical and accessible nutritional programmes for this population.

Poorer self-rated health in residential areas with limited healthcare supply

AIMS

The aim of this study was to explore differences in self-rated health and physician-diagnosed disease across geographical regions in Iceland to better understand regional requirements for health services.

METHODS

Data on self-rated health and diagnosed disease from a 2007 national health survey (n=5909; response rate 60.3%) across geographic regions were analysed. Area of residence was classified according to distance from the Capital Area (CA) and availability of local health services. We used regression models to calculate crude and multivariable adjusted odds ratios (aOR) and corresponding 95% confidence intervals (95% CI) of self-rated health and diagnosed diseases by area of residence. Models were adjusted for age, gender, education, civil status, and income.

RESULTS

Residents in rural areas with no local health service supply rated their physical health worse than residents of areas with diverse supply of specialised services (aOR 1.40, 95% CI 1.21-1.61). Residents outside the CA rate both their physical (aOR 1.35, 95% CI 1.23-1.50) and mental (aOR 1.17, 95% CI 1.06-1.30) health worse than residents in the CA. In contrast, we observed a lower prevalence of several diagnosed chronic diseases, including cancers (aOR 0.78, 95% CI 0.60-0.99) and cardiovascular disease (aOR 0.77, 95% CI 0.62-0.95) outside the CA.

CONCLUSIONS

These findings from a national survey of almost 6000 Icelanders indicate that self-rated health is related to regional healthcare supply. The findings have implications for national planning of health services aiming at equality both in health and access to health services.

Body mass index and overweight in relation to residence distance and population density: experience from the Northern Finland birth cohort 1966

Background

The effect of urban sprawl on body weight in Finland is not well known. To provide more information, we examined whether body mass index (BMI) and the prevalence of overweight are associated with an individual’s distance to the local community centre and population density in his/her resident area.

Methods

The sample consisted of 5363 men and women, members of the Northern Finland Birth Cohort 1966 (NFBC), who filled in a postal questionnaire and attended a medical checkup in 1997, at the age of 31 years. Body mass index (BMI; kg/m²) and the prevalence of overweight (BMI ≥ 25.0 kg/m²) were regressed on each subject’s road distance to the resident commune’s centre and on population density in the 1 km² geographical grid in which he/she resided, using a generalized additive model. Adjustments were made for sex, marital status, occupational class, education, leisure-time and occupational physical activity, alcohol consumption and smoking.

Results

The mean BMI among the subjects was 24.7 kg/m², but it increased by increasing road distance (by 1.3 kg/m² from 5–10 to 20–184 km) and by decreasing population density (by 1.7 kg/m² from 1000–19,192 to 1–5 inhabitants/km²). The respective increases in overweight (overall prevalence 41%) were 13 per cent units for distance and 14 per cent units for population density. Adjusted regressions based on continuous explanatory variables showed an inverse L-shaped pattern with a mean BMI of 24.6 kg/m² at distances shorter than 5 km and a rise of 2.6 kg/m² at longer distances, and an increase of 2.5 kg/m² from highest to lowest population density. The associations with road distance were stronger for women than men, while the sex difference in association with population density remained indeterminate.

Conclusions

We conclude that young adults in Northern Finland who live far away from local centres or in the most sparsely populated areas are fatter than those who live close to local centres or in densely populated areas. The likely explanations include variations in everyday physical activity in different residential environments, although causality of the associations remains to be confirmed.

Patient assessment of chronic illness care, glycemic control and the utilization of community health care among the patients with type 2 diabetes in Shanghai, China

OBJECTIVES

To evaluate the relationship between Patient Assessment of Chronic Illness Care in community health centers and self-management behaviors and glycemic control and to examine the relationship between Patient Assessment of Chronic Illness Care in community health centers and the utilization of community health centers for monitoring and treating diabetes among the patients with type 2 diabetes.

METHODS

A questionnaire including self-management behaviors, glycemic control, Patient Assessment of Chronic Illness Care in community health centers and the most often utilized medical institutions for monitoring and treating diabetes (community health centers vs. hospitals) was administered to 960 patients with type 2 diabetes in Shanghai, China. The relationships between Patient Assessment of Chronic Illness Care and self-management behaviors, self-management behaviors and glycemic control, Patient Assessment of Chronic Illness Care and glycemic control, Patient Assessment of Chronic Illness Care and the most often utilized medical institutions for monitoring and treating diabetes were examined.

RESULTS

Wilcoxon rank sum tests showed that the high scores of total Patient Assessment of Chronic Illness Care and five subscales in community health centers were positively related to almost all the proper self-management behaviors and good glycemic control (p<0.05). Almost all of the proper self-management behaviors were positively related to good glycemic control (p<0.01). High summary score of the Patient Assessment of Chronic Illness Care was positively associated with the utilization of community health centers for monitoring and treating diabetes (p<0.001).

CONCLUSIONS

Patient Assessment of Chronic Illness Care (implementation of the Chronic Care Model) in community health centers was associated with patients' self-management behaviors and glycemic control, and finally was associated with the utilization of community health centers for monitoring and treating diabetes.

Socioeconomic status and differences in medication use among older people according to ATC categories and urban–rural residency

Aims: To study how selected indicators of socioeconomic status and urban–rural residency associate with medication use in form of number of daily medications, polypharmacy, and medication use according to Anatomic Therapeutic Classification (ATC) system. Methods: Cross-sectional, population-based study among older community-dwelling Icelanders. Criteria for participation were: age ≥65 years, community-dwelling, and able to communicate verbally and to set up a time for a face-to-face interview. Information on medication use was obtained by interviews and by examining each person’s medication record. Medications were categorised according to ATC system. A questionnaire and the physical and mental health summary scales of SF-36 Health Survey were used to assess potential influential factors associated with medication use. Results: On average, participants ( n=186) used 3.9 medications, and the prevalence of polypharmacy was 41%. No indicators of socioeconomic status had significant association to any aspects of medication use. Compared to urban residents, rural residents had more diagnosed diseases, were less likely to live alone, were less likely to report having adequate income, and had fewer years of education. Controlling for these differences, urban people were more likely to use medication from the B and C categories. Moreover, older urban men, with worse physical health, and greater number of diagnosed diseases used more medications from the B category. Conclusions: There are unexplained regional differences in medications use, from categories B and C, by older Icelanders. Further studies are needed on why urban residents used equal number of medications, or even more medications, compared to rural residents, despite better socioeconomic status and fewer diagnosed diseases.

Longitudinal changes in functional capacity: effects of socio-economic position among ageing adults

Introduction

Health and functional capacity have improved especially in Western countries over the past few decades. Nevertheless, the positive secular trend has not been able to decrease an uneven distribution of health. The main aim of this study was to follow-up changes in functional capacity among the same people in six years time and to detect whether the possible changes vary according to socio-economic position (SEP). In addition, it is of interest whether health behaviours have an effect on these possible changes.

Methods

This longitudinal follow-up study consisted of 1,898 individuals from three birth cohorts (1926–1930, 1936–40, 1946–50) who took part in clinical check-ups and answered to a survey questionnaire in 2002 and 2008. A sub-scale of physical functioning from the RAND-36 was used to measure functional capacity. Education and adequacy of income were used as indicators of socio-economic position. Repeated-measures ANOVA was used as a main method of analysis.

Results

Physical functioning in 2002 and 2008 was poorest among those men and women belonging to the oldest cohort. Functional capacity deteriorated in six years among men in the oldest cohort and among women in all three cohorts. Socio-economic disparities in functional capacity among ageing people existed. Especially lower adequacy of income was most consistently associated with poorer functional capacity. However, changes in functional capacity by socio-economic position remained the same or even narrowed independent of health behaviours.

Conclusion

Socio-economic disparities in physical functioning are mainly incorporated in the level of functioning at the baseline. No widening socioeconomic disparities in functional capacity exist. Partly these disparities even seem to narrow with ageing.
