The influencing factors of health-related quality of life among rural hypertensive individuals: a cross-sectional study

Secular trends of dental caries and association with nutritional status: a retrospective analysis of 16,199 Chinese students from three successive national surveys from 2010 to 2019

Introduction

The prevalence of dental caries (DC) among students in developing countries has increased at an alarming rate, and nutritional status has been shown to be associated with DC in children and adolescents with inconsistent conclusions. We aimed to understand the trends of DC prevalence in students aged 7, 9, 12, and 14 years and to explore the relationship between DC prevalence and nutritional status.

Methods

We recruited 16,199 students aged 7, 9, 12, and 14 years in China by multi-stage, stratified, random sampling methods from 2010 to 2019. Permanent caries were measured using the Decay, Loss, and Filling (DMF) index and prevalence rate. Deciduous caries were measured using the decay, loss, and filling (dmf) index and prevalence rate. Nutritional status was assessed using body mass index (BMI) and hemoglobin levels. Logistic regression analysis was used to assess the association between nutritional status and the DC prevalence in children and adolescents, incorporating information concerning family-related factors.

Results

The results indicated that DC prevalence increased from 39.75% in 2010 to 53.21% in 2019 in Henan province, with deciduous teeth and permanent teeth being 45.96 and 27.18%, respectively, in 2019. The total caries rate decreased with age (p < 0.05), and the caries rate of girls was higher than that of boys in 2019 (55.75% vs. 50.67%) (p < 0.001). The prevalence of dental caries among primary and secondary school students in areas with medium economic aggregate was the highest, followed by cities with the best economic development level, and cities with low economic levels have a lower prevalence of dental caries. The dental caries prevalence was negatively correlated with body mass index. In the fully adjusted model, underweight children had a higher caries prevalence (OR = 1.10, 95%CI: 0.86-1.41). Children with anemia had a higher prevalence of dental caries (OR = 1.18, 95%CI: 0.98-1.42).

Conclusion

The DC prevalence of students in Henan Province was high, with a tendency to increase. Females, young individuals, and those with a higher economic level showed a positive correlation with the prevalence of caries. In the process of economic development, particular attention should be paid to early childhood caries prevention. Nutritional status should be taken seriously among children and adolescents, and the oral health system should be improved to keep pace with economic development.

Association of long COVID with health-related Quality of Life and Social Participation in Germany: Finding from an online-based cross-sectional survey

Purpose

This study aims to examine the health-related Quality of Life (hrQoL) and social participation in participants with Long COVID compared to participants without symptoms after COVID-19 and participants with no prior SARS-CoV-2 infection.

Methods

A cross-sectional online survey was conducted in Germany. The non-random sample consists of participants 18 years or older. Participants were divided in three groups: Lg COVID with a prior SARS-CoV-2 infection and new or persistent symptoms 28 days after infection, ExCOVID with a prior SARS-CoV-2 infection and without new or persistent symptoms after 28 days, and NoCOVID when participants had no prior SARS-CoV-2 infection. EQ-5D-3L was used as hrQoL measure and the Index for the Assessment of Health Impairments (IMET) to reflect social participation. Descriptive and inferential statistics were performed.

Results

A total of 3188 participants were included in the analysis (1421 Lg COVID, 260 ExCOVID, 1507 NoCOVID). Lg COVID was associated with the lowest EQ-5D-3L index values (p < 0.001), Visual Analogue Scale (VAS) scores (p < 0.001), and IMET (p < 0.001) scores followed by NoCOVID and ExCOVID. After adjusting for sociodemographic and medical conditions in a multivariable model Long COVID was still associated with lower hrQoL compared to NoCOVID (p < 0.001). About 10% of Lg COVID participants showed no health impairments in all EQ-5D dimensions while 51.1% of NoCOVID and 60% of ExCOVID participants showed no health impairments.

Conclusion

This study highlights the impairments of persons with Long COVID on hrQoL and social participation compared to individuals without Long COVID in Germany.

The Relation Between Osteoporosis and Bone Fractures and Health-Related Quality of Life in Post-menopausal Saudi Women in the Jazan Region: A Cross-Sectional Study

INTRODUCTION

Osteoporosis is a significant health concern, often leading to fragility fractures and severely impacting the quality of life in post-menopausal women. Studies evaluating the effects of osteoporosis and resultant fractures on health-related quality of life (HRQoL) in Saudi women are lacking. This study aimed to assess the relationship between osteoporosis and fracture and physical, psychological, social, and environmental HRQoL domains in post-menopausal Saudi women.

METHODS

In this cross-sectional study conducted in Jazan, Saudi Arabia, 158 post-menopausal Saudi women completed HRQoL surveys using the validated Arabic WHOQOL-BREF questionnaire. Data on socioeconomics, comorbidities, and fracture history were gathered. Descriptive statistics delineated sample characteristics. Analysis of variance (ANOVA) and post-hoc tests identified differences in HRQoL across socioeconomic and clinical categories. Multivariate regression analyses determined factors independently related to HRQoL.

RESULTS

Of 158 women surveyed, 39% had a history of osteoporotic fracture. Foot (35%), hand (31%), and vertebral (10%) fractures were the most frequent. Women over 70 had significantly lower physical HRQoL than those aged 45-55 (p<0.001). Unemployed and lower-income women showed poorer HRQoL across domains (p<0.01). Vertebral and hand fractures were negatively related to physical and psychological health (p<0.05). Chronic diseases like hypertension and rheumatoid arthritis reduced HRQoL (p<0.01). In regression analyses, older age, vertebral fracture, physical inactivity, long-term hormone therapy, and unemployment emerged as determinants of poorer HRQoL (p<0.05).

CONCLUSION

Osteoporosis and resultant fragility fractures, especially in vertebral and hand bones, led to substantial impairments in physical, social, psychological, and environmental HRQoL in Saudi women. Modifiable risk factors like physical inactivity and long-term hormone use also affected HRQoL. Targeted screening and multidomain interventions for disadvantaged women with osteoporosis are warranted to improve functioning and quality of life.

Association between medication adherence and health-related quality of life of patients with hypertension and dyslipidemia

PURPOSE

Τo evaluate the association between medication adherence and health-related quality of life (HRQoL) of patients with hypertension and dyslipidemia in Greece.

METHODS

In a multicenter, cross-sectional, non-interventional study, a total of 721 hypertensive and 463 dyslipidemic adult outpatient patients were recruited during the COVID-19 pandemic using consecutive sampling. The EQ-5D-5L instrument was used to measure HRQoL, and medication adherence was assessed with the Adherence Starts with Knowledge 20 questionnaire. Multiple linear stepwise regressions using robust standard errors were employed.

RESULTS

Approximately 28% of hypertensive and 16% of dyslipidemic patients had not been fully adherent during the previous week, while the estimates were 49 and 34%, respectively when the previous month was considered. The HRQoL domain with the highest prevalence of problems was anxiety/depression, followed by mobility and usual activities for both conditions; HRQoL was lower in dyslipidemic patients. Higher medication non-adherence was independently associated with lower EQ-VAS in hypertension and a lower EQ-5D index in dyslipidemia. Other significant risk factors of impaired HRQoL and general health were lack of exercise, longer duration of disease, and multimorbidity, while a curvilinear effect of BMI and age was observed. Also, female gender, employment, and marriage worked as protective factors for hypertensive patients and education for dyslipidemic participants.

CONCLUSION

Medication adherence is suboptimal in patients with hypertension and, in particular, with dyslipidemia in Greece. Moreover, poor medication adherence has a detrimental impact on patients' HRQoL. Therefore, improving treatment outcomes and patients' HRQoL in a sustainable way requires a better understanding of the factors influencing medication adherence.

Health-related quality of life among ethnic minority residents in remote Western China: a cross-sectional study

BACKGROUND

Paying attention to the health-related quality of life (HRQOL) of rural residents in poverty-stricken areas is an important part of China's poverty alleviation, but most studies on health-related quality of life have focused on rural residents, elderly individuals, and patients; evidence on the HRQOL of rural minority residents is limited. Thus, this study aimed to assess the HRQOL of rural Uighur residents in remote areas of Xinjiang, China, and determine its influencing factors to provide policy opinions for realizing a healthy China strategy.

METHODS

A cross-sectional study was performed on 1019 Uighur residents in rural areas. The EQ-5D and self-administered questionnaires were used to assess HRQOL. We applied Tobit and binary logit regression models to analyse the factors influencing HRQOL among rural Uighur residents.

RESULTS

The health utility index of the 1019 residents was - 0.197,1. The highest proportion of respondents reporting any problem was for mobility (57.5%), followed by usual activity (52.8%). Low levels of the five dimensions were related to age, smoking, sleep time, Daily intake of vegetables and fruit per capita. Gender, age, marital status, physical exercise, sleep duration, daily intake of cooking oil per capita, daily intake of fruit per capita, distance to the nearest medical institution, non-infectious chronic diseases (NCDs), self-rated health score, and participation in community activities were correlated with the health utility index of rural Uighur residents.

CONCLUSIONS

HRQOL was lower for rural Uyghur residents than for the general population. Improving health behavioural lifestyles and reducing the incidence of poverty (return to poverty) due to illness are effective means of promoting the health in Uyghur residents. The region must fulfil the health poverty alleviation policy and focus on vulnerable groups and low-income residents to improve the health, ability, opportunity, and confidence of this population to live well.

Differences in Health-Related Quality of Life and Its Associated Factors Among Older Adults in Urban and Rural Areas

Purpose

Urban-rural health disparity is one of the most prominent challenges in China today. The goal of this study is to find differences in health-related quality of life (HRQoL) and its associated factors among older people in urban and rural areas.

Methods

A multi-stage stratified sampling method was conducted in Shanxi Province, with a total of 3250 older adults participated in this cross-sectional survey. HRQoL was assessed using the Chinese version of the EQ-5D-5L. Tobit regression models were employed to identify associated factors for HRQoL.

Results

The mean EQ-5D utility score of the total sample was 0.87± 0.23, with a statistically significant difference observed between urban (0.89 ± 0.22) and rural areas (0.86 ± 0.23). Obesity (Coe=−0.10, p=0.021) and nutrition awareness (Coe=−0.14, p=0.009) were two unique associated factors to rural older adults’ HRQoL. While, age (Urban: Coe=0.13, p=0.001; Rural: Coe=−0.019, p<0.001), socioeconomic status (Urban: Coe=0.13, p<0.001; Rural: Coe=0.14, p<0.001), number of chronic non-communicable diseases (Urban: Coe=−0.20, p<0.001; Rural: Coe=−0.15, p<0.001), sleep quality (Urban: Coe=−0.22, p<0.001; Rural: Coe=0.15, p<0.001) and daytime sleepiness (Urban: Coe=−0.13, p<0.001; Rural: Coe=−0.13, p<0.001) were found to be associated with HRQoL regardless of the residential area.

Conclusion

This study suggested that rural older adults are facing HRQoL disadvantages compared to those in urban area. Accordingly, more attention should be devoted to rural older adults’ HRQoL, particularly to the unique factors like body weight and nutrition awareness. Targeted policies and interventions should be implemented to improve HRQoL and bridge the urban-rural HRQoL gap.
