Diabetes and coronary heart disease in Filipino-American women: role of growth and life-course socioeconomic factors

A low-inflammatory diet is associated with a lower incidence of diabetes: role of diabetes-related genetic risk

BACKGROUND

Whether a low-inflammatory diet relates to type 2 diabetes risk remains unclear. We examined the association between a low-inflammatory diet and risk of type 2 diabetes among normoglycemic and prediabetic participants. We also explored whether a low-inflammatory diet modifies genetic risk for type 2 diabetes.

METHODS

Among 142,271 diabetes-free UK Biobank participants (aged 39-72 years), 126,203 were normoglycemic and 16,068 were prediabetic at baseline. Participants were followed for up to 15 years to detect incident type 2 diabetes. At baseline, dietary intake was assessed with a 24-h dietary record. An inflammatory diet index (IDI) was generated based on high-sensitivity C-reactive protein levels and was a weighted sum of 34 food groups (16 anti-inflammatory and 18 pro-inflammatory). Participants were grouped into tertiles corresponding to inflammatory level (low, moderate, and high) based on IDI scores. Prediabetes at baseline was defined as HbA1c 5.7-6.4% in diabetes-free participants. Incident type 2 diabetes and age of onset were ascertained according to the earliest recorded date of type 2 diabetes in the Primary Care and Hospital inpatient data. A diabetes-related genetic risk score (GRS) was calculated using 424 single-nucleotide polymorphisms. Data were analyzed using Cox regression and Laplace regression.

RESULTS

During follow-up (median 8.40 years, interquartile range 6.89 to 11.02 years), 3348 (2.4%) participants in the normoglycemia group and 2496 (15.5%) in the prediabetes group developed type 2 diabetes. Type 2 diabetes risk was lower in normoglycemic (hazard ratio [HR] = 0.71, 95% confidence interval [CI] 0.65, 0.78) and prediabetic (HR = 0.81, 95% CI 0.73, 0.89) participants with low IDI scores compared to those with high IDI scores. A low-inflammatory diet may prolong type 2 diabetes onset by 2.20 (95% CI 1.67, 2.72) years among participants with normoglycemia and 1.11 (95% CI 0.59, 1.63) years among participants with prediabetes. In joint effect analyses, normoglycemic or prediabetes participants with low genetic predisposition to type 2 diabetes and low IDI scores had a significant 74% (HR = 0.26, 95% CI 0.21, 0.32) or 51% (HR = 0.49, 95% CI 0.40, 0.59) reduction in type 2 diabetes risk compared to those with high genetic risk plus high IDI scores. There were significant additive and multiplicative interactions between IDI and GRS in relation to type 2 diabetes risk in the normoglycemia group.

CONCLUSIONS

A low-inflammatory diet is associated with a decreased risk of type 2 diabetes and may delay type 2 diabetes onset among participants with normal blood glucose or prediabetes. A low-inflammatory diet might significantly mitigate the risk of genetic factors on type 2 diabetes development.

A healthy lifestyle mitigates the risk of heart disease related to type 2 diabetes: a prospective nested case-control study in a nationwide Swedish twin cohort

AIMS/HYPOTHESIS

We aimed to examine the association between type 2 diabetes and major subtypes of heart disease, to assess the role of genetic and early-life familial environmental factors in this association and to explore whether and to what extent a healthy lifestyle mitigates the risk of heart disease related to type 2 diabetes.

METHODS

In this prospective nested case-control study based on the Swedish Twin Registry, 41,463 twin individuals who were aged ≥40 and heart disease-free were followed up for 16 years (from 1998 to 2014) to detect incident heart disease. Type 2 diabetes was ascertained from self-report, the National Patient Registry and glucose-lowering medication use. Heart disease diagnosis (including coronary heart disease, cardiac arrhythmias and heart failure) and onset age were identified from the National Patient Registry. Healthy lifestyle-related factors consisted of being a non-smoker, no/mild alcohol consumption, regular physical activity and being non-overweight. Participants were divided into three groups according to the number of lifestyle-related factors: (1) unfavourable (participants who had no or only one healthy lifestyle factor); (2) intermediate (any two or three); and (3) favourable (four). Generalised estimating equation models for unmatched case-control design and conditional logistic regression for co-twin control design were used in data analyses.

RESULTS

Of all participants, 2304 (5.5%) had type 2 diabetes at baseline. During the observation period, 9262 (22.3%) had any incident heart disease. In unmatched case-control analyses and co-twin control analyses, the multi-adjusted OR and 95% CI of heart disease related to type 2 diabetes was 4.36 (3.95, 4.81) and 4.89 (3.88, 6.16), respectively. The difference in ORs from unmatched case-control analyses vs co-twin control analyses was statistically significant (OR 1.57; 95% CI 1.42, 1.73; p < 0.001). In stratified analyses by type 2 diabetes, compared with an unfavourable lifestyle, an intermediate lifestyle or a favourable lifestyle was associated with a significant 32% (OR 0.68; 95% CI 0.49, 0.93) or 56% (OR 0.44; 95% CI 0.30, 0.63) decrease in heart disease risk among patients with type 2 diabetes, respectively. There were significant additive and multiplicative interactions between lifestyle and type 2 diabetes on heart disease.

CONCLUSIONS/INTERPRETATION

Type 2 diabetes is associated with more than fourfold increased risk of heart disease. The association still remains statistically significant, even after fully controlling for genetic and early-life familial environmental factors. However, greater adherence to a healthy lifestyle may significantly mitigate the risk of heart disease related to type 2 diabetes. Graphical abstract.

Rates of Current Tobacco and Electronic Smoking Device Use Among Filipinos in Hawai'i

Tobacco use continues to damage the health of Filipinos. In Hawai'i, Filipinos have the second highest rate of smoking among adults and they are the fastest growing minority population. Electronic smoking devices are becoming popular and accessible. This study explored attitudes and practices of Filipinos in Hawai'i who use electronic smoking devices (ESDs), as well their knowledge of the effect of smoking and/or vaping on health and their awareness and motivations use smoking cessation programs. A convenience sample of 178 Filipinos who reported that they smoked and/or vaped responded to the online survey from January to March 2018. Reasons for starting to use ESDs included liking the different flavors (43%), being curious about vaping (38%), and viewing vaping as healthier than cigarettes (30%). Among respondents, 12% said they would like to quit smoking and 11% wanted to quit vaping, and very few felt that smoking and/or vaping behaviors impacted their health. They also demonstrated limited knowledge of cessation methods and products. Tobacco and vaping cessation programs for the Filipino community in Hawai'i are much needed because this population is at risk of developing smoking-related diseases.

Engaging the ASEAN Diaspora: Type 2 Diabetes Prevalence, Pathophysiology, and Unique Risk Factors among Filipino Migrants in the United States

Type 2 diabetes prevalence is rising rapidly in Southeast Asia (SEA) where urbanization and adoption of ‘western’ behavioral lifestyles are attributed as predominant risk factors. The Southeast Asian diaspora to the United States has resulted in a sizable portion of migrant and US born SEAs, with approximately 4 million Filipino Americans, 2 million Vietnamese-Americans, Cambodians (330,000), and Thai (300,000) as the most populous. Their longer exposure to a western lifestyle and participation in clinical studies with other racial/ethnic groups, provide opportunities to evaluate etiologic factors which might inform trends and intervention opportunities among residents of Southeast Asia.

Epidemiologic studies in the US have identified higher T2D prevalence among Filipinos (16.1%) compared to groups perceived to be at highest risk for T2D, namely Latinos (14.0%), Black (13.7%), and Native Americans (13.4%), while SEAs (including Burmese, Cambodian, Indonesian, Laotian, Malaysian, and Thai, 10.5%) and Vietnamese (9.9%) had higher T2D risk compared to Whites (7.7%), despite their absence of general obesity. Asian-Americans, including SEAs, East and South Asians, collectively have higher rates of undiagnosed T2D compared to other racial/ethnic groups in the US. Almost half (44%) of Filipinos with newly diagnosed T2D have isolated post-challenge hyperglycemia and will remain undiagnosed if current screening practices remain limited to measures of glycosylated hemoglobin and fasting plasma glucose.

The University of California San Diego Filipino Health Study found excess visceral adipose tissue accumulation, low ratio of muscle to total abdominal mass area, low adiponectin concentration, multiparity (≥ 6 live births), and sleep insufficiency (<7 hours) to be unique T2D risk factors among Filipino-American women, even after adjusting for established T2D risk factors including hypertension and parental history of T2D. Social determinants such as low educational attainment (less than college completion), and sustained social disadvantage during childhood and adulthood were independently associated with T2D risk. Gestational diabetes is a known risk factor for future T2DM among women; Northern California data shows that following Asian Indians, gestational diabetes was highest among Filipina and SEA parturients, who had twice the GDM prevalence as Black, Hispanic, and White women. Identification of novel T2D risk factors among SEAs may guide early diagnosis, inform pathophysiology, and identify unique opportunities for T2D prevention and management.

Negotiating health and chronic illness in Filipino-Australians: a qualitative study with implications for health promotion

OBJECTIVE

In spite of the healthy immigrant effect, the prevalence of lifestyle-related chronic diseases among migrants is reported to approximate that of the host country with longer duration of stay. For example, higher rates of chronic diseases such as Type 2 diabetes and hypertension have been observed among Filipino migrants and these have been linked to acculturation. The aim of this study was to explore the experiences of Filipino-Australian migrants in managing their chronic health conditions in a Western host country.

DESIGN

This paper reports on qualitative findings of a mixed methods study that used an explanatory sequential design. Nine focus group discussions were undertaken with 58 Filipino-Australian migrants with chronic disease. Thematic analysis was undertaken using a five-stage general purpose thematic framework ensuring that themes closely identified key participants' experiences .

RESULTS

Findings revealed that health benefits provided by the health system in Australia were considered advantageous. However, a lack of social and instrumental support compounded isolation and disempowerment, limiting self-management strategies for chronic illnesses. Cultural beliefs and practices influenced their knowledge, attitude to and management of chronic disease, which health service providers overlooked because of perceived acculturation and English language skills. Overall this study has clearly identified recognition of cultural beliefs, language needs and support as three core needs of Filipino-Australian migrants with the elderly the most vulnerable.

CONCLUSION

This paper highlights that self-management of chronic disease among elderly Filipino immigrants may be adversely affected by host language difficulties, a lack of social support and cultural issues, impacting on access to services, health-seeking behaviours and participation in health promotion initiatives. Language, culture-specific health interventions and resources and enhancing social support are likely important strategies in promoting chronic disease self-management among the elderly. These interventions have the potential to empower and encourage individuals to take control and better manage their chronic disease.

Diabetes among non-obese Filipino Americans: Findings from a large population-based study

OBJECTIVES

Filipino Americans form the second-largest Asian American and Pacific Islanders subgroup. Growing evidence suggests that Filipino Americans have higher rates of diabetes than non-Hispanic whites. The key objectives of this study are 1) to determine the prevalence of diabetes in non-obese Filipino Americans compared to non-obese non-Hispanic whites, and 2) to identify risk factors for diabetes in non-obese Filipino men and women.

METHODS

Secondary analysis of population-based data from combined waves (2007, 2009 and 2011) of the adult California Health Interview Survey (CHIS). The study sample was restricted to non-obese Filipino Americans (n = 1629) and non-Hispanic whites (n = 72 072).

RESULTS

Non-obese Filipino Americans had more than twice the odds of diabetes compared to non-Hispanic whites, even after correcting for several known risk factors (OR = 2.80, p < 0.001). For non-obese Filipino men, older age, poverty, cigarette smoking, and being overweight are associated with increased odds for diabetes, while older age was the only factor associated with diabetes among Filipina women.

DISCUSSION

Diabetes prevention approaches need to be targeted towards non-obese Filipino Americans, due to their high risk of diabetes.

One size does not fit all: cardiovascular health disparities as a function of ethnicity in Asian-American women

OBJECTIVE

Although few studies have examined cardiovascular disease in Asian-American subgroups separately, limited data in Asian Americans strongly suggest that some subgroups are at increased risk. The present study examined modifiable cardiovascular risk factor profiles as a function of Asian ethnicity.

METHODS

This descriptive cross-sectional pilot study recruited Asian-American women (N=147) in northeast Florida including Cambodians (n=39), Chinese (n=36), Filipinos (n=49), and Vietnamese (n=23). Risk factors included blood pressure, body mass index, waist circumference and blood lipids.

RESULTS

Filipino participants (41%) had ≥4 risk factors compared to 21% Cambodian, 13% Vietnamese and 0% Chinese. The Chinese had significantly more participants (44%) with the absence of CVD risk factors compared to all other subgroups. Obesity rate (18%), mean BMI: 26 ± 5 kg/m(2) and mean triglycerides (173 ± 103 mg/dL) were highest in Filipinas (n=49). The Chinese (n=36) had a low rate (4%) of obesity with a mean BMI of 23 ± 3 kg/m(2) and the least risk factors along with the lowest triglycerides (88 ± 44 mg/dL). Cambodians (n=39; BMI of 24 ± 3 kg/m(2)) and Vietnamese (n=23; BMI: 22 ± 3 kg/m(2)) had low rates of obesity with comparable rates of unhealthy lipids and hypertension as the Filipinas.

CONCLUSIONS

Modifiable CVD risk factor profiles significantly differed as a function of ethnicity supporting the premise that Asian-American women cannot be categorized as one group and the traditional "one size fits all" prevention or treatment of CVD risk factors should be re-considered.

Assessment of heart disease knowledge and risk factors among first-generation Filipino Americans residing in Southern Nevada: A cross-sectional survey

Objective

Filipino Americans are the second largest Asian subgroup in the United States and heart disease is their leading cause of death. Despite this, they remain an invisible minority and experience health disparities in cardiovascular health. Prior to implementing and designing health promotion programs, it is important to assess their level of knowledge about heart disease and to identify their risk factors.

Purpose

We examined the baseline knowledge of heart disease among first-generation Filipino Americans and the risk factors prevalent among them.

Method

A convenience sample of 300 Filipino Americans aged 35-75 years completed the Heart Disease Fact Questionnaire to assess their knowledge of heart disease and a researcher-developed questionnaire to assess the heart disease risk factors. Data were collected in Southern Nevada in the fall of 2011. Descriptive statistics, correlations, and multiple regression were used for data analysis.

Result

The sample had an average knowledge score of 82.81% out of a maximum correct score of 100%. The risk factors prevalent among them included: hypertension (47.7%), diabetes (14%), dyslipidemia (27.7%), overweight (36.7%), abdominal obesity (80.6%), smoking (11.7%), and lack of exercise (48%).

Conclusion

Heart disease is the leading cause of death among Filipino Americans. In this study, Filipino Americans had adequate knowledge of heart disease but many reported having risk factors. Understanding the behavioral determinants of heart disease knowledge and specific risk factors is helpful in designing effective health prevention strategies. Early screening targeting the younger generation is also important to help detect the risk factors in their earliest stages. The screening results may also induce individuals to take action.

Components of height and blood pressure in childhood

BACKGROUND

In children being taller is associated with higher blood pressure (BP), but few studies have divided height into its components: trunk and leg length. We examined the associations of total height, trunk length and leg length with systolic BP (SBP), diastolic BP (DBP) and pulse pressure (PP) at early childhood and mid-childhood visits, as well as change between the two visits.

METHODS

We obtained five measures of SBP and DBP at the early childhood visit (N = 1153, follow-up rate = 54%) and at the mid-childhood visit (N = 1086, follow-up rate = 51%) respectively, in Project Viva, a US cohort study. We measured total height and sitting height (a measure of trunk length that includes head and neck) and calculated leg length as the difference between the two. Using mixed models, we adjusted the cross-sectional analyses for leg length when trunk length was the exposure of interest, and vice versa. We also adjusted for maternal race/ethnicity, child age, sex, overall adiposity and BP measurement conditions.

RESULTS

At the mid-childhood visit, total height was positively associated with SBP [0.34 (0.24; 0.45) mmHg/cm] but not with DBP [0.07 (-0.003; 0.15)]. In models examining trunk and leg length separately, each was positively associated with SBP [0.72 (0.52; 0.92) and 0.33 (0.16; 0.49) respectively]. In a fully adjusted model with both leg and trunk length, only trunk length remained associated with BP. For a given leg length, a 1-cm increment in trunk length was associated with a 0.63-mmHg (0.42; 0.83) higher SBP and a 0.17-mmHg (0.02; 0.31) higher DBP. For a given trunk length, however, the associations of leg length with SBP [0.13 (-0.03; 0.30)] and with DBP [0.002 (-0.11; 0.12)] were null. These patterns were similar at the early childhood visit.

CONCLUSIONS

Children with greater trunk lengths have higher BPs, perhaps because of the additional pressure needed to overcome gravity to perfuse the brain.

Prevalence of metabolic syndrome among Filipino-Americans: a cross-sectional study

AIM

The aims of this study are a) to examine the prevalence of metabolic syndrome among Filipino-Americans, b) to compare the rate of metabolic syndrome between Filipino men and women, and c) to examine the prevalence of central adiposity.

BACKGROUND

Filipino-Americans are the second largest Asian subgroup in the United States and their leading cause of death is coronary heart disease (CHD).

METHODS

This study utilized a descriptive correlational, cross-sectional design that included a convenience sample of 300 Filipino-Americans residing in Southern Nevada. Survey questionnaires were used to collect the sample's demographic data and presence of CHD risk factors. Waist circumference measurements were used to examine central adiposity.

RESULTS

Metabolic syndrome and central adiposity are highly prevalent among Filipino-Americans residing in Southern Nevada. More men than women had the syndrome, but the rate of central adiposity was significantly higher in women than in men.

CONCLUSIONS

Intensive lifestyle modifications and treatment are indicated to decrease the prevalence of metabolic syndrome and the risk of heart disease in this group.

Short leg length, a marker of early childhood deprivation, is associated with metabolic disorders underlying type 2 diabetes: the PROMISE cohort study

OBJECTIVE

Short leg length, a marker of early childhood deprivation, has been used in studies of the association of early life conditions with adult chronic disease risk. The objective of this study was to determine the cross-sectional associations of leg length with measures of insulin sensitivity and β-cell function.

RESEARCH DESIGN AND METHODS

Subjects (n = 462) at risk for type 2 diabetes were recruited into the PROspective Metabolism and ISlet cell Evaluation (PROMISE) longitudinal cohort. Leg length was calculated from sitting and standing height at the 3-year clinical examination. Glucose tolerance status was determined using an oral glucose tolerance test. Insulin sensitivity was assessed using homeostasis model assessment of insulin resistance (HOMA-IR) and the Matsuda insulin sensitivity index (ISI), while the insulinogenic index over HOMA-IR (IGI/IR) and the insulin secretion sensitivity index 2 (ISSI-2) determined β-cell function. Multiple linear regression analysis was conducted, adjusting for covariates including age, sex, ethnicity, family history of diabetes, waist, and weight.

RESULTS

Leg length and leg-to-height ratio were significantly associated with HOMA-IR (β = -0.037, β = -10.49, respectively; P < 0.0001), ISI (β = 0.035, β = 8.83, respectively; P < 0.0001), IGI/IR (β = 0.021, P < 0.05; β = 7.60, P < 0.01, respectively), and ISSI-2 (β = 0.01, P < 0.03; β = 3.34, P < 0.01, respectively) after adjustment for covariates. The association of shorter leg length with lower insulin sensitivity was most evident for those with high waist circumferences.

CONCLUSIONS

Shorter legs were independently associated with lower insulin sensitivity and β-cell function, suggesting that early childhood deprivation may increase the risk of developing diabetes.

Trends of edentulism among middle-aged and older Asian Americans

OBJECTIVES

We estimated national trends of the prevalence of edentulism (complete tooth loss) for Asian American subgroups in the United States and investigated factors that could contribute to improvements in edentulism across populations over time.

METHODS

We used 10 waves of the National Health Interview Survey data collected from 1999 to 2008. Eligible respondents were those aged 50 years and older who completed the question on tooth loss. We contrasted the odds and probabilities of edentulism over time in Chinese, Filipinos, Asian Indians, and other Asians with those in Whites, Blacks, and Hispanics.

RESULTS

The rates of edentulism differed substantially across Asian subgroups. Compared with Whites, Chinese and other Asians had a lower risk of being edentulous, whereas being Filipino increased the odds. The rate for Asian Indians was similar to that for Whites. Nonetheless, rates of decline were similar across the Asian population groups.

CONCLUSIONS

Asian Americans are heterogeneous in edentulism. Innovative and sustainable public health programs and services are essential to prevent oral health diseases and conditions.

A systematic review of overweight, obesity, and type 2 diabetes among Asian American subgroups

This systematic review synthesizes data published between 1988 and 2009 on mean BMI and prevalence of overweight, obesity, and type 2 diabetes among Asian subgroups in the U.S. We conducted systematic searches in Pub- Med for peer-reviewed, English-language citations that reported mean BMI and percent overweight, obesity, and diabetes among South Asians/Asian Indians, Chinese, Filipinos, Koreans, and Vietnamese. We identified 647 database citations and 23 additional citations from hand-searching. After screening titles, abstracts, and full-text publications, 97 citations remained. None were published between 1988 and 1992, 28 between 1993 and 2003, and 69 between 2004 and 2009. Publications were identified for the following Asian subgroups: South Asian (n=8), Asian Indian (n=20), Chinese (n=44), Filipino (n=22), Korean (n= 8), and Vietnamese (n=3). The observed sample sizes ranged from 32 to 4245 subjects with mean ages from 24 to 78 years. Among samples of men and women, the lowest reported mean BMI was in South Asians (22.1 kg/m(2)), and the highest was in Filipinos (26.8 kg/m(2)). Estimates for overweight (12.8-46.7%) and obesity (2.1-59.0%) were variable. Among men and women, the highest rate of diabetes was reported in Asian Indians with BMI ≥ 30 kg/m(2) (32.9%, age and sex standardized). This review suggests heterogeneity among U.S. Asian populations in cardiometabolic risk factors, yet comparisons are limited due to variability in study populations, methods, and definitions used in published reports. Future efforts should adopt standardized methods to understand overweight, obesity and diabetes in this growing U.S. ethnic population.

Migration of women from the Philippines: implications for healthcare delivery

Filipinos have been an important part of the global workforce since the first half of the twentieth century. The initial migration of primarily men has shifted to an increasing numbers of women in recent decades. These changes are primarily attributed to a high demand for domestic workers, nurses and occupations that are female dominated. In 2005, about 70% of the international Labour migrants are women from the Philippines. Living in a foreign land, these women face challenges that affect their physical, emotional and social well being. Especially on their first year living abroad, these women experience significant stress which affects their health as they adjust to a new work environment, culture, social norms, diet, and weather. The emotional strain can be greater for those who have left their families behind in the Philippines and aggravated by the financial need to send money to them. Striking examples, such as the homicide rate of Filipino women married to Australian men being 5.6 times higher than that of Australian-born women, underscores the importance of supportive health care environments and appreciating socio-cultural factors. In the delivery of healthcare services to migrant women, it is critical to consider the unique socio-cultural background of women as well as health beliefs and practices.

A review of the literature: evaluating dietary intake of Filipino Americans at risk for type 2 diabetes

The purpose of this literature review is to investigate the research on the dietary intake of Filipino Americans. Evaluating the dietary practices of Filipino Americans may have an effect on the development of type 2 diabetes. Data collection was obtained, and four databases were included: Pub Medical, Cumulative Index of Nursing and Allied Health Literature, Journals at OVID, and Medline. The key words used in the search were "diet,""type 2 diabetes," and "Filipinos." A total of nine articles were relevant and met the inclusion criteria. The following articles were excluded: studies in a foreign language, letters to the editor, and program descriptions.

Foot self-care practices among Filipino American women with type 2 diabetes mellitus

INTRODUCTION

To determine the foot self-care practices performed by Filipino American (FA) women with type 2 diabetes mellitus (DM).

METHOD

The Summary of Diabetes Self Care Activities - Revised and Expanded measure was administered to 118 FA adult female immigrants with type 2 DM.

RESULTS

Younger FA women (<65 years), participants with higher education, those who immigrated to the United States (US) at younger ages, and participants diagnosed with type 2 DM at younger ages reported they washed their feet every day during the past week. Moreover, FA women who immigrated to the US at younger ages and participants who were diagnosed with the disease at younger ages reported that they dried their feet (in between toes) daily during the previous week. Further, FA women who were diagnosed with type 2 DM at younger ages were more likely to report that they checked their feet every day during the past week, when compared with participants who were diagnosed with the disease at older ages. Finally, most FA women did not inspect the inside of their shoes.

CONCLUSION

Foot self-care practices were less frequently performed by older FA women with type 2 DM (≥65 years), making them more prone to the development of foot problems such as ulcers, infections, and disfigurations. Optimum foot self-care practices must be encouraged in older FA women to prevent such foot problems, and subsequent amputations.

Self-care behaviors of Filipino-American adults with type 2 diabetes mellitus

AIM

To examine the diabetes self-care behaviors of Filipino-American (FA) adults with type 2 diabetes mellitus (DM).

METHOD

The Summary of Diabetes Self Care Activities-Revised and Expanded measure was administered to 192 (74 males and 118 females) FA adult immigrants with type 2 DM.

RESULTS

Older FAs (> or =65 years), females, those who were older when they immigrated, and participants diagnosed with type 2 DM longer were more likely to follow recommended medication regimens. Younger FAs (<65 years) and participants diagnosed with type 2 DM for shorter duration of time were less likely to perform blood glucose testing. Most FAs reported following their eating plans; however, those who lived in the United States (US) longer followed healthful eating plans. Likewise, females reported eating five or more servings of fruits and/or vegetables daily. Moreover, older FAs reported evenly spacing carbohydrate intake everyday. Furthermore, older participants, those with less education, participants who were older when they immigrated, and those older when diagnosed with type 2 DM ate fewer foods high in fats. As to physical activity, FA males and participants with higher education exercised more frequently.

CONCLUSION

Younger FAs were less likely to perform optimum type 2 DM self-care behaviors pertaining to diet, medication taking, and blood glucose testing compared to their older counterparts. This finding suggests an increased risk for type 2 DM comorbidities and/or complications in younger FAs, which may require more intensive treatments in later years.

How does socioeconomic development affect risk of mortality? An age-period-cohort analysis from a recently transitioned population in China

During the 20th century, the Hong Kong Chinese population experienced 2 abrupt but temporally distinct macroenvironmental changes: The transition from essentially preindustrial living conditions to a rapidly developing economy through mass migration in the late 1940s was followed by the emergence of an infant and childhood adiposity epidemic in the 1960s. The authors aimed to delineate the effects of these 2 aspects of economic development on mortality, thus providing a sentinel for other rapidly developing economies. Sex-specific Poisson models were used to estimate effects of age, calendar period, and birth cohort on Hong Kong adult mortality between 1976 and 2005. All-cause and cause-specific mortality, including mortality from ischemic heart disease (IHD), cardiovascular disease excluding IHD, lung cancer, other cancers, and respiratory disease, were considered. Male mortality from IHD and female mortality from other cancers increased with birth into a more economically developed environment. Cardiovascular disease mortality increased with birth after the start of the infant and childhood adiposity epidemic, particularly for men. Macroenvironmental changes associated with economic development had sex-specific effects over the life course, probably originating in early life. The full population health consequences of these changes are unlikely to manifest until persons who have spent their early lives in such environments reach an age at which they become vulnerable to chronic diseases.

Mid- and late-life diabetes in relation to the risk of dementia: a population-based twin study

OBJECTIVE

We aimed to verify the association between diabetes and the risk of dementia, Alzheimer's disease, and vascular dementia in twins and to explore whether genetic and early-life environmental factors could contribute to this association.

RESEARCH DESIGN AND METHODS

This study included 13,693 twin individuals aged > or =65 years. Dementia was diagnosed according to DSM-IV (Diagnostic Manual of Mental Disorders, 4th ed.) criteria. Information on diabetes was collected from the inpatient registry and self- or informant-reported history of diabetes. Data were analyzed following two strategies: 1) unmatched case-control analysis for all participants using generalized estimating equation (GEE) models and 2) cotwin matched case-control analysis for dementia-discordant twin pairs using conditional logistic regression.

RESULTS

Of all participants, 467 were diagnosed with dementia, including 292 with Alzheimer's disease and 105 with vascular dementia, and an additional 170 were diagnosed with questionable dementia. Diabetes was present in 1,396 subjects. In GEE models, diabetes was associated with adjusted odds ratios (ORs) (95% CI) of 1.89 (1.51-2.38) for dementia, 1.69 (1.16-2.36) for Alzheimer's disease, and 2.17 (1.36-3.47) for vascular dementia. Compared with late-life diabetes (onset age > or =65 years), the risk effect of mid-life diabetes (onset age <65 years) on dementia was stronger. Conditional logistic analysis of 210 dementia-discordant twin pairs led to ORs of 2.41 (1.05-5.51) and 0.68 (0.30-1.53) for dementia related to mid- and late-life diabetes, respectively.

CONCLUSIONS

Diabetes increases the risk of Alzheimer disease and vascular dementia. The risk is stronger when diabetes occurs at mid-life than in late life. Genetic and early-life environmental factors might contribute to the late-life diabetes-dementia association but could not account for the mid-life diabetes-dementia association.

The effect of age at migration on cardiovascular mortality among elderly Mexican immigrants

PURPOSE

In this study, we evaluated the influence of age at migration on cardiovascular mortality among older Mexican Americans immigrants.

METHODS

A population-based cohort of Mexican-origin (N = 907) participants ages 60+ was followed up to 8 years. The association between migration before age 20 compared with after age 20 and mortality was analyzed with the use of multivariate Cox proportional models.

RESULTS

Compared with those who migrated later, those who migrated before the age of 20 years had higher income and education, were more likely to speak English, were culturally more Anglo, and more likely to be men. Immigration before 20 years of age was associated with greater rates of cardiovascular mortality (hazard ratio, 2.39; 95% confidence interval, 1.16 - 4.94) compared with those migrating at older ages, even after adjustment for age, sex, education, income, and baseline cardiovascular health. No age at migration differences were observed for noncardiovascular deaths.

CONCLUSIONS

Mexican Americans who migrated in early life experienced greater cardiovascular disease death rates than later migrants. Early experiences related to migration may have consequences for late-life disease that are not mitigated by the higher socioeconomic status achieved by early migrants. Health or economic selection related to migration may play a role although accounting for health and socioeconomic status actually increased differences between early and later migrants.

Does the relationship between waist circumference, morbidity and mortality depend on measurement protocol for waist circumference?

There is currently no consensus regarding the optimal protocol for measurement of waist circumference (WC), and no scientific rationale is provided for any of the WC protocols recommended by leading health authorities. A panel of experts conducted a systematic review of 120 studies (236 samples) to determine whether measurement protocol influenced the relationship of WC with morbidity of cardiovascular disease (CVD) and diabetes and with mortality from all causes and from CVD. Statistically significant associations with WC were reported for 65% (152) of the samples across all outcomes combined. Common WC protocols performed measurement at the minimal waist (33%), midpoint (26%) and umbilicus (27%). Non-significant associations were reported for 27% (64) of the samples. Most of these protocols measured WC at the midpoint (36%), umbilicus (28%) or minimal waist (25%). Significant associations were observed for 17 of the remaining 20 samples, but these were not significant when adjustment was made for covariates. For these samples, the most common WC protocols were the midpoint (35%) and umbilicus (30%). Similar patterns of association between the outcomes and all WC protocols were observed across sample size, sex, age, race and ethnicity. Our findings suggest that WC measurement protocol has no substantial influence on the association between WC, all-cause and CVD mortality, CVD and diabetes.
