“…If more than one person was age-eligible, one was randomly selected. Where the selected respondent is married and the spouse resides in the same household, they are also recruited for the study regardless of their age [23]. All interviews are conducted in person by trained full-time interviewers of the Mexican National Statistics Institute (Instituto Nacional de Estadistica y Geografia, INEGI).…”

BackgroundThe Satisfaction with Life Scale (SWLS) has been widely used and has proven to be a valid and reliable instrument for assessing satisfaction with life in diverse population groups, however, research on satisfaction with life and validation of different measuring instruments in Mexican adults is still lacking. The objective was to evaluate the psychometric properties of the Satisfaction with Life Scale (SWLS) in a representative sample of Mexican adults.MethodsThis is a methodological study to evaluate a satisfaction with life scale in a sample of 13,220 Mexican adults 50 years of age or older from the 2012 Mexican Health and Aging Study. The scale’s reliability (internal consistency) was analysed using Cronbach’s alpha and inter-item correlations. An exploratory factor analysis was also performed. Known-groups validity was evaluated comparing good-health and bad-health participants. Comorbidity, perceived financial situation, self-reported general health, depression symptoms, and social support were included to evaluate the validity between these measures and the total score of the scale using Spearman’s correlations.ResultsThe analysis of the scale’s reliability showed good internal consistency (α = 0.74). The exploratory factor analysis confirmed the existence of a unique factor structure that explained 54% of the variance. SWLS was related to depression, perceived health, financial situation, and social support, and these relations were all statistically significant (P < .01). There was significant difference in life satisfaction between the good- and bad-health groups.ConclusionsResults show good internal consistency and construct validity of the SWLS. These results are comparable with results from previous studies. Meeting the study’s objective to validate the scale, the results show that the Spanish version of the SWLS is a reliable and valid measure of satisfaction with life in the Mexican context.

“…The aim and design of the MHAS have been published elsewhere [9, 10]. In brief, the three waves of the MHAS (2001, 2003, and 2012) contained a representative sample of community-dwelling Mexican older adults (≥50 years old) and their respective spouses (≥18 years old).…”

Summary Vitamin D deficiency was common in older adults from a country with adequate sun exposure. The variables associated with this deficiency provide insight into the next steps needed to characterize older adults with this deficiency and to treat it accordingly. Purpose The aim of this study was to describe the prevalence of and factors associated with vitamin D deficiency among Mexican older adults. Methods This was a secondary analysis of the last wave of the Mexican Health and Aging Study. Vitamin D levels along with other biomarkers were obtained from a sub-sample of Mexican adults older than 60 years. Prevalence was described by sex and age group, and a multivariate analysis was performed to test the factors associated with this condition. Results Data from 1088 adults over the age of 60 years were analyzed. The mean serum vitamin D level was 23.1 ± 8.1 ng/mL and was significantly higher among men than women (25.6 ± 0.6 and 22.8 ± 0.5 ng/mL, respectively; p < 0.001). In total, 37.3% (n = 406) presented with vitamin D deficiency, 65% of whom were women. Low 25-(OH)-vitamin D levels were associated with female sex (OR 1.74, 95% CI 1.59–2.42), current smoking (OR 2.21, 95% CI 1.47–3.39), education (OR 1.1, 95% CI 1.06–1.13), physical activity (OR 1.74, 95% CI 1.31–2.23), and high levels of glycated hemoglobin (OR 1.16, 95% CI 1.07–1.25). Conclusions Vitamin D deficiency was highly prevalent in Mexican older adults and was associated with a number of factors, indicating the multifactorial causality of this deficiency.

“…1). No significant difference was found in the percentage of self-reported diabetes between the subsample and the national sample (17.9% vs. 18.9%) of MHAS [16]. Also, the prevalence of self-reported diabetes in the MHAS national sample has been externally validated and compared with the national prevalence from Mexican National Health and Nutrition Survey data [16].…”

Purpose The purpose of the study was to examine the prevalence and determinants of prediabetes, undiagnosed diabetes, and diabetes among Mexican adults from a subsample of the Mexican Health and Aging Study. Methods We examined 2012 participants from a subsample of the Mexican Health and Aging Study. Measures included sociodemographic characteristics, body mass index, central obesity, medical conditions, cholesterol, high-density lipoprotein cholesterol, hemoglobin A1c, and vitamin D. Logistic regression was performed to identify factors associated with prediabetes, undiagnosed diabetes, and self-reported diabetes. Results Prevalence of prediabetes, undiagnosed, and self-reported diabetes in this cohort was 44.2%, 18.0%, and 21.4%, respectively. Participants with high waist-hip ratio (1.61, 95% confidence interval [CI] = 1.05–2.45) and high cholesterol (1.85, 95% CI = 1.36–2.51) had higher odds of prediabetes. Overweight (1.68, 95% CI = 1.07–2.64), obesity (2.38, 95% CI = 1.41–4.02), and high waist circumference (1.60, 95% CI = 1.06–2.40) were significantly associated with higher odds of having undiagnosed diabetes. Those residing in a Mexican state with high U.S. migration had lower odds of prediabetes (0.61, 95% CI = 0.45–0.82) and undiagnosed diabetes (0.53, 95% CI = 0.41–0.70). Those engaged in regular physical activity had lower odds of undiagnosed diabetes (0.74, 95% CI = 0.57–0.97). Conclusions There is a high prevalence of prediabetes and undiagnosed diabetes among Mexican adults in this subsample. Findings suggest the need for resources to prevent, identify, and treat persons with prediabetes and undiagnosed diabetes.
