“…In addition, the analysis of anthropometric data of the women group showed an effect of country on fat distribution, with significant differences in waist circumference. Recently, Aleman-Mateo and colleagues provided evidence that elderly Mexican men and women have significantly less FFM and more total and central fat compared to African-American and Caucasian elderly (47). Similarly in this study by country there were significant differences within gender in height, body composition and fat distribution as evaluated by waist circumference.…”

“…Older Mexican adults are known to have less muscle mass and greater visceral adiposity than non-Hispanic Whites and Blacks in the U.S., suggesting that behavioral factors associated with these age-related changes may mediate the association between functional declines and risk for metabolic disease. 28 Indeed, we found that diabetes prevalence was 14.0% and 19.5% greater in weak men and women compared to their stronger counterparts, respectively. Moreover, a recent study by Kumar et al 29 demonstrated that older obese Mexicans are at a greater risk for physical disability than their non-obese counterparts.…”

Background The risk of cardiovascular problems due to diabetes mellitus is highest among older Mexicans, and yet what remains to be determined is the association between muscle weakness and diabetes in this population. Therefore, the purpose of this study was to determine the association between muscle strength and diabetes among Mexican adults greater than 50 years old. Design Cross-sectional. Setting National sample of households in both urban and rural areas. Participants A sub-sample of 1,841 individuals, aged 50 years and older, was included from the 2012 Mexican Health and Aging Study (MHAS). Measurements Strength was assessed using a hand-held dynamometer, and the single largest reading from either hand was normalized to body mass (NGS). Conditional inference tree analyses were used to identify sex-specific NGS weakness thresholds. Linear regression was used to examine the association between NGS and HbA1c, and logistic regression was used to assess the association between weakness and risk of diabetes (HbA1c ≥6.5% [≥48 mmol/mol]), after controlling for age, sex and waist circumference. Results Normalized grip strength was inversely associated with HbA1c (β=−1.56; p<0.001). Optimal sex-specific NGS weakness thresholds to detect diabetes were ≤0.46 and ≤0.30 for men and women respectively. Weakness was associated with significantly increased odds of diabetes (OR: 1.69, 95%CI: 1.37-2.10), even after adjusting for age, sex, and waist circumference. Conclusions NGS was robustly associated with diabetes and other cardiometabolic risk factors in older Mexicans. This simple screen may serve as a valuable tool to identify adults that are at risk for negative health consequences or early mortality, and that might benefit from lifestyle interventions to reduce risk.

“…This result may be partially attributed to the different body fat composition between racial and ethnic groups. Previous studies have shown that blacks and Hispanics have a greater body fat and waist circumference than whites for the same BMI . Presumably, abdominal fat may be more important than total obesity for disability in older adults …”

Objectives To examine racial/ethnic differences in the effects of body mass index (BMI) on the onset of functional impairment over 10 years of follow-up. Design Longitudinal analyses of a cohort from a nationally representative survey of community-dwelling American adults. Setting Six waves (1996-2006) of US Health and Retirement Study (HRS). Participants Two groups of HRS participants aged ≥50 without functional impairment at baseline (1996): 5,884 with no mobility difficulty, and 8,484 with no Activities of Daily Living (ADLs) difficulty. Measurements Mobility difficulty was a composite measure of difficulty in walking several blocks, walking one block, climbing several flights of stairs, and climbing one floor of stairs. ADL difficulty was measured by difficulty in dressing, bathing or showing, eating, and getting in or out of bed without help. The association between the baseline BMI categories and risk to develop functional impairment was estimated using generalized estimating equations (GEE) models. Results Overweight and obesity were significant predictors for functional impairment. Compared to the Whites in the same overweight and obese categories, Hispanics were 41% and 91% more likely to develop ADL disability. Blacks in the overweight and severely obese categories were also more likely than their White counterparts to develop ADL disability. Risk of developing ADL difficulty was higher for Hispanics than for Blacks in the obese category. For onset of mobility difficulty, no significant differences were found across racial/ethnic groups within any BMI Category. Conclusion Blacks and Hispanics were at higher risk than Whites for ADL but not mobility impairment. In addition to weight control, prevention efforts should promote exercise to reduce functional impairment, especially for Blacks and Hispanics, who are at higher risk.
