IntroductionWe estimated the prevalence and correlates of mild cognitive impairment (MCI) among middle-aged and older diverse Hispanics/Latinos.MethodsMiddle-aged and older diverse Hispanics/Latinos enrolled (n = 6377; 50–86 years) in this multisite prospective cohort study were evaluated for MCI using the National Institute on Aging–Alzheimer's Association diagnostic criteria.ResultsThe overall MCI prevalence was 9.8%, which varied between Hispanic/Latino groups. Older age, high cardiovascular disease (CVD) risk, and elevated depressive symptoms were significant correlates of MCI prevalence. Apolipoprotein E4 (APOE) and APOE2 were not significantly associated with MCI.DiscussionMCI prevalence varied among Hispanic/Latino backgrounds, but not as widely as reported in the previous studies. CVD risk and depressive symptoms were associated with increased MCI, whereas APOE4 was not, suggesting alternative etiologies for MCI among diverse Hispanics/Latinos. Our findings suggest that mitigating CVD risk factors may offer important pathways to understanding and reducing MCI and possibly dementia among diverse Hispanics/Latinos. 相似文献
BackgroundPuerto Rican adults residing in the US mainland experience a high prevalence of metabolic syndrome (MetS). A diet containing healthy protein-rich sources may help control risk factors for MetS.ObjectiveThis study aimed to evaluate 2-year longitudinal associations between intake of various protein-rich foods and changes in the six MetS components.DesignThis is a secondary analysis of a longitudinal cohort study using data from the baseline (2004–2007) and 2-year follow-up visits (2006–2011) in the Boston Puerto Rican Health Study.Participants/settingParticipants were self-identified Puerto Ricans, aged 45 to 75 years, residing in Boston, Massachusetts, or the surrounding area (n = 1,126).Main outcome measuresMetS components were fasting glucose, high-density lipoprotein (HDL) cholesterol, triglycerides, systolic and diastolic blood pressures, and waist circumference.Statistical analysisBaseline intake of foods reported in a semiquantitative food frequency questionnaire were expressed as servings/day, and protein-rich foods were categorized as unprocessed white meat, unprocessed red meat, processed meat, milk and yogurt, cheese, fish and seafood, beans, nuts, and eggs. Associations between each continuous protein food group and continuous 2-year change in MetS components were assessed using linear mixed models adjusted for socioeconomic and behavioral factors, and other dietary sources.ResultsThe top contributors to total protein intake were unprocessed red meat (13.3%) and unprocessed poultry (13.0%), and the lowest were eggs (2.92%) and nuts (0.91%). Higher intake of processed meats was associated with an increase in waist circumference over 2 years (β = 1.28; standard error [SE] = 0.63), whereas higher intake of fish and seafood was associated with a decrease in waist circumference (β = ?3.47; SE = 1.39). Intake of unprocessed poultry was associated with a decrease in triglycerides (β = ?24.5; SE = 9.13). No other significant associations were observed between protein sources and 2-year changes in MetS components.ConclusionsConsuming less processed meat and more fish and seafood and unprocessed poultry was associated with decreases in waist circumference and triglycerides among US mainland Puerto Ricans. Other dietary protein sources were not related to cardiometabolic health. 相似文献
Despite the presumed health benefits, Latinas are less likely than women from other ethnic groups to receive adequate prenatal care during their pregnancy. However, it is unclear whether this trend is the result of political economic conditions that limit access of many Latinos in the United States to adequate health services in general, or of sociocultural conditions that restrict the use of such services even when they are made available. Furthermore, it is unclear whether these barriers pose a risk for adverse birth outcomes in this population. To address these issues, we conducted a two-phase study of the political economic and sociocultural barriers to use of prenatal care services among Mexican and Mexican American women living in San Diego, California, and their association with adverse birth outcomes in this population. A quantitative assessment of information abstracted from the medical records of 173 Latinas who had given birth at a university medical center found that absence of Medi-Cal benefits or other forms of health insurance was the only significant predictor of inadequate prenatal care during pregnancy. However, neither lack of insurance nor adequate prenatal care was associated with any adverse birth outcomes. A qualitative analysis of information obtained from interviews of 30 Latinas receiving prenatal care services at a medical clinic for the homeless and medically underserved residents of San Diego identified three major themes underlying the lack of adequate prenatal care: lack of trust in formal versus informal institutions, wanted versus unwanted pregnancies, and the importance of the social network.相似文献
Objectives. Mexican Americans (MAs), compared to white non‐Hispanics (WNHs), have higher rates of biliary disease, noninsulin dependent diabetes, and endstage renal disease but lower rates of lung cancer, hip fractures, and mortality from coronary heart disease. Relatively little research has been done to identify other ethnic differences in disease incidence. We used surgical procedure rates to confirm known ethnic differences and to explore our clinical suspicion that MAs have higher rates of appendectomy than WNHs.
Methods. We used a registry of surgical procedures at two teaching hospitals in South Texas to calculate proportional operation ratios (PORs) for MAs versus WNHs. These two hospitals are the primary source of acute hospital care for the indigent in the area. The POR is arithmetically identical to proportional incidence and mortality ratios.
Results. MAs underwent appendectomy proportionally more often than WNHs at both hospitals (POR = 1.41 and 1.75, p < 0.0001). Other significant PORs were consistent with known ethnic disease differences in biliary tract operations, vascular access for chronic hemodialysis, lung cancer, and coronary artery bypass.
Conclusions. These findings support the hypothesis that MAs may undergo appendectomy more often than WNHs and so may be at higher risk of appendicitis. 相似文献
Objective. The object of this study was to investigate whether there are differences in survival by ethnicity in people with AIDS.
Design. The CDC Public Access Dataset was analysed. To estimate survival more accurately, a cohort of individuals diagnosed in 1987 was chosen from the dataset. Using this analysis, probabilities of survival were estimated.
Results. There were significant differences in survival in blacks and Hispanics as compared to whites diagnosed in 1987. Although there are differences in survival by transmission category, survival differences by ethnicity persisted when analysed within specific transmission categories. A model where the frequency distributions of survival were log‐transformed suggests that disease progression per se may not be the most important factor, but time of diagnosis may be. In addition, in looking at median survival by year of diagnosis, it is clear that blacks and Hispanics have not shown the same magnitude of improvement in survival time, and lag behind whites.
Conclusions. This study clearly shows differences in survival with AIDS by ethnicity. Differential access to health care may underlie such ethnic differences in survival. 相似文献
PurposeHigher levels of acculturation among Latinos have been shown to be associated with a higher prevalence of cardiovascular (CV) risk factors in some studies of middle-age persons. The association of acculturation and prevalence of CV risk factors in elderly Latinos is less well established.MethodsAcculturation was measured using the validated bidimensional Acculturation Rating Scale for Mexican Americans-II. We conducted a cross-sectional analysis of the association of acculturation with prevalence of CV risk factors among 1789 elderly men and women from the Sacramento Area Latino Study on Aging using multivariate linear and logistic regression. We tested for the interaction of acculturation with risk factors by nativity status.ResultsMedian age was 69.8 years. Higher acculturation was associated with lower systolic blood pressure, lower low-density lipoprotein, higher high-density lipoprotein, and lower prevalence of CV disease after age and sex adjustment. Higher acculturation remained associated with lower level of low-density lipoprotein and higher level of high-density lipoprotein after full adjustment. Nativity status did not affect these results.ConclusionsContrary to other reports in middle-aged persons, higher levels of acculturation were associated with better lipid profiles and no significant differences in other CV risk factors by acculturation level in elderly Latinos. 相似文献
We modeled associations of quantity and frequency of alcohol use with depressive symptoms (negative affect, lack of positive affect, somatic disturbance, interpersonal problems) in two household surveys of Mexican-Americans (Ns = 1,313 and 3,577). Multivariate analyses controlled cultural (immigration, acculturation) and demographic (age, income, household size, marital status, employment status) characteristics, and assessed interactions of these two classes of predictors. Alcohol use was inconsistently related to depression. In some analyses, cultural characteristics accounted for associations of alcohol use with depression. In others, associations of alcohol use with depression depended on cultural characteristics. Associations of drinking with depression tended not to be robust across samples 相似文献
Summary A geographically based sample of 1069 Hispanic and non-Hispanic white persons aged 20–74 years, living in southern Colorado
and who tested normal on an oral glucose tolerance test (World Health Organization criteria) were evaluated to determine associations
of dietary factors with fasting serum insulin concentrations. Subjects were seen for up to three visits from 1984 to 1992.
A 24-h diet recall and fasting insulin concentrations were collected at all visits. In longitudinal data analysis, lower age,
female gender, Hispanic ethnicity, higher body mass index, higher waist circumference, and no vigorous activity were significantly
related to higher fasting insulin concentrations. High total and saturated fat intake were associated with higher fasting
insulin concentrations after adjusting for age, sex, ethnicity, body mass index, waist circumference, total energy intake
and physical activity. Dietary fibre and starch intake were inversely associated with fasting insulin concentrations. No associations
with fasting insulin concentrations were observed for monounsaturated fat, polyunsaturated fat, sucrose, glucose and fructose
intake. Associations were similar in men and women and for active and inactive subjects, though associations of fibre and
starch intake with insulin concentrations were strongest in lean subjects. These findings support animal studies and a limited
number of human population studies which have suggested that increased saturated and total fat intake and decreased fibre
and starch intake increase fasting insulin concentrations and may also increase insulin resistance. These findings, which
relate habitual macronutrient consumption to hyperinsulinaemia in a large population, may have implications for studies attempting
primary prevention of non-insulin-dependent diabetes mellitus. [Diabetologia (1997) 40: 430–438]

ObjectiveTo explore the role of feeding practices and food purchases in toddler dietary intake and anthropometry.MethodsA convenience sample of Latino mother and toddler pairs were interviewed at baseline and at 6-month follow-up. Data on feeding practices, toddler dietary intake, anthropometry, and food purchases were collected using the Toddler-Feeding Questionnaire; 24-hour recalls; measurements of weight, height, and/or length; and food purchase receipts.ResultsIndulgent feeding scores and high intake of sweetened beverage were associated with a 0.52 increase (P = .03) and 0.46 increase in toddler weight-for-height z-score (P = .05), respectively. Households with 10 percentage points of more sweetened food and beverage expenditures were associated with increases in weight indicator z-scores.Conclusions and ImplicationsIndulgent feeding, high intake, and purchase of sweetened beverage are associated with weight gain in Latino toddlers. Programs should target food purchasing decisions and provide concrete guidance for the division of responsibility around feeding. 相似文献
