Abstract Objective This study examined the influence of depressive symptoms on health-related quality of life (HRQOL) among community-dwelling older adults suffering from various categories of ...chronic comorbidity. Methods A population-based survey in adults aged 60 years or more was conducted within a random sample of 1085 beneficiaries of the Mexican Institute of Social Security in Mexico City. Depressive symptoms were evaluated with the 15-item Geriatric Depression Scale, and chronic comorbidity was determined with self-reports concerning prior medical diagnoses and the HRQOL Short Form-36 health survey. We carried out a stratified analysis by comorbidity category, evaluating the impact of depressive symptoms on HRQOL through an analysis of variance and modeling the independent association of depression symptoms with HRQOL using multiple linear regression analyses adjusted for comorbidity and other covariables. Results HRQOL scores were low in the presence of depressive symptoms, while their impact increased when chronic diseases were also present. The group with the poorest HRQOL was older adults suffering from both depressive symptoms and two or more chronic diseases ( P <.05). The stratified analysis by comorbidity and multivariate analysis, adjusted for covariables, indicated that depressive symptoms and comorbidity had cumulative negative effects on HRQOL. Conclusion The HRQOL of older adults deteriorated when depressive symptoms were present and decreased even further with the simultaneous occurrence of chronic illnesses. Identifying depression symptoms—either alone or along with chronic conditions—is crucial for implementation of measures aimed at improving elderly people's HRQOL.
Objective:
To systematically review published articles reporting the use of smoking cessation mobile health (mHealth) interventions in Latin America.
Methods:
Five different databases were searched ...from database inception to 2020. Criteria: (1) the research was a smoking cessation randomized controlled trial (RCT), quasi-experimental research, or single-arm study; (2) the intervention used at least one type of mHealth intervention; (3) the research was conducted in Latin American; and (4) the research reported the cessation rate.
Results:
Of the seven selected studies, four were conducted in Brazil, two in Mexico, and one in Peru. Only one study was an adequately powered RCT. Interventions relied on text messages (n = 3), web-based tools (n = 2), and telephone calls (n = 3). Some studies (n = 4) provided pharmacotherapy support. Smoking cessation outcomes included self-reported (n = 5) and biochemically verified (n = 2) abstinence. Follow-ups were conducted at Month 6 (n = 2), Week 12 (n = 4), and Day 30 (n = 1). Cessation rates varied from 9.4% at Week 12 to 55.5% at Day 30.
Conclusion:
Despite the promising cessation rates of mHealth interventions in Brazil, Mexico, and Peru, there is a need to rigorously evaluate these interventions in different Latin American countries with RCTs that are long-term, adequately powered, and use biochemical verification of cessation.
Although body fat percent (BF%) may be used for screening metabolic risk factors, its accuracy compared to BMI and waist circumference is unknown in a Mexican population. We compared the ...classification accuracy of BF%, BMI and WC for the detection of metabolic risk factors in a sample of Mexican adults; optimized cutoffs as well as sensitivity and specificity at commonly used BF% and BMI international cutoffs were estimated. We also estimated conditional BF% means at BMI international cutoffs.
We performed a cross-sectional analysis of data on body composition, anthropometry and metabolic risk factors(high glucose, high triglycerides, low HDL cholesterol and hypertension) from 5,100 Mexican men and women. The association between BMI, WC and BF%was evaluated with linear regression models. The BF%, BMI and WC optimal cutoffs for the detection of metabolic risk factors were selected at the point where sensitivity was closest to specificity. Areas under the ROC Curve (AUC) were compared among classifiers using a non-parametric method.
After adjustment for WC, a 1% increase in BMI was associated with a BF% rise of 0.05 percentage points (p.p.) in men (P<0.05) and 0.25 p.p. in women (P<0.001). At BMI=25.0 predicted BF% was 27.6±0.16 (mean±SE) in men and 41.2±0.07 in women. Estimated BF% cutoffs for detection of metabolic risk factors were close to 30.0 in men and close to 44.0 in women. In men WC had higher AUC than BF% for the classification of all conditions whereas BMI had higher AUC than BF% for the classification of high triglycerides and hypertension. In womenBMI and WC had higher AUC than BF% for the classification of all metabolic risk factors.
BMI and WC were more accurate than BF% for classifying the studied metabolic disorders. International BF% cutoffs had very low specificity and thus produced a high rate of false positives in both sexes.
This study examined the influence of migration status, nativity and country of residence on joint associations of physical activity (PA) and sedentary behavior (SB) in anthropometric indicators of ...Mexicans and Mexican-Americans living in the US and in Mexico.
We examined data from two large national surveys, the National Health and Nutrition Examination Survey from the US (NHANES, 2011⁻2012) and Mexico (ENSANUT, 2012). Using self-reported minutes of moderate to vigorous physical activity and SB, we calculated four categories for analyses. Anthropometric measures consisted of body mass index (BMI) and waist circumference (WC). We used data of migration status, nativity and country of residence. Linear regression models examined how joint categories of PA and SB were associated with BMI and WC according to migration status, nativity and country of residence, controlling for health risk behaviors.
Analyses showed that even among those in the category with the lowest risk behavior, "physically active and low sedentary", there were differences in BMI and WC by migration status, nativity and country of residence. Within this lower risk category, Mexican immigrants living in the US had the greatest association with high BMI, while US-born Mexican-Americans living in the US had the highest WC values when compared with the group of Mexicans living in Mexico.
Joint categories of PA and SB were associated with BMI and WC by migration status, nativity and country of residence among populations with Mexican ethnicity.
Objective: To evaluate the effect of physical activity (PA) on the risk of depression among Mexican adults over a 6-year follow-up period. Method: We evaluated longitudinal data from the Health ...Worker Cohort Study, which follows employees of the Mexican Institute for Social Security in Morelos State, Mexico, over time. Depressive symptoms and PA were assessed at baseline and at a follow-up measurement 6 years later. The study population was free of depressive symptomatology at baseline, as assessed by the Center for Epidemiological Studies−Depression Scale (CES-D). After 6 years, the CES-D was completed once again by the participants to estimate their risk of depression based on the different PA patterns they reported during the follow-up period. PA was estimated using a questionnaire that has been applied in similar longitudinal studies and has been validated in Spanish, with metabolic equivalents (METs) as the unit of measurement. We identified three PA patterns: highly active, moderately active, and inactive. The relative risk of depression (CES-D score ≥ 16 points) was estimated using multivariate logistical regression analysis according to the PA patterns at a follow-up measurement 6 years later. Results: The incidence of depression after 6 years was higher among inactive participants (16.5%) than among those with an active PA pattern (10.6%). We found that more active PA patterns have an important protective effect against depression. The odds ratio (OR) for the more active PA patterns was 0.46, 95% confidence interval (CI) 0.25, 0.87, and for individuals with a moderately active PA pattern, the OR was 0.57, 95% CI 0.34, 0.93. These ORs were obtained after adjusting for confounding variables and baseline PA levels. Conclusion: Our results indicate that PA may reduce risk of depression in Mexican adults. These findings have potential applications for depression prevention programs in target populations with similar social and cultural contexts.

This study aimed to characterize the patterns of smoking, e-cigarette use, other substance use (alcohol and marijuana), and depression by sexual orientation in a sample of Mexican adult smokers.
Data ...came from a 2018-2020 (six waves) online survey of adult smokers, recruited from a commercial research panel (92.5% heterosexual,
= 4786; 3.1% lesbian/gay,
= 160; and 4.4% bisexual,
= 229). After stratifying the data by sex, logistic, multinomial, and linear logistic regression models were estimated (depending on the outcome), including as independent variables sexual orientation (i.e., gay/lesbian, bisexual, heterosexual = Reference), age, education, household income, and wave.
Being a gay male was independently associated with greater smoking dependence (β = 0.20; 95% confidence interval CI: 0.02 to 0.39), greater likelihood of preference for flavored capsule cigarettes (adjusted odds ratio AOR = 2.10, 95% CI: 1.33 to 3.28), and depression diagnosis (AOR = 2.85, 95% CI: 1.64 to 4.95). Bisexual males had higher e-cigarette dependence (β = 0.37; 95% CI: 0.05 to 0.68, among dual users only) and were more likely to have been diagnosed with depression (AOR = 2.34, 95% CI: 1.30 to 4.18). Lesbian females were more likely to prefer menthol cigarettes (AOR = 3.32, 95% CI: 1.60 to 6.86), to have used marijuana more than once (AOR = 3.23, 95% CI: 1.83 to 5.72), and to have depressive symptoms (AOR = 1.85, 95% CI: 1.04 to 3.29). Bisexual females had a greater likelihood of depressive symptoms (AOR = 1.71, 95% CI: 1.14 to 2.56) and depression diagnosis (AOR = 2.22, 95% CI: 1.43 to 3.42).
Lesbian, gay, and bisexual adult smokers in Mexico appear more likely than heterosexual adult smokers to report having depression. Substance use and depression among sexual minority populations need to be addressed further.
The aim of this study was to examine various psychosocial, behavioral, and socio-environmental factors in a multiethnic sample of healthy-weight, overweight, and obese youths in the United States ...(US) and Mexico and determine differences by sex. We conducted a cross-sectional analysis of 633 youths aged 11-18 years who completed a self-reported questionnaire. Height and weight were measured to determine body mass index (BMI). Overweight and obese youth in both countries were significantly more likely to report a higher body image dissatisfaction (Odds Ratio (OR) = 1.67 and OR= 2.95, respectively), depressive symptoms (OR = 1.08 and OR = 1.12, respectively), perceive themselves as overweight (OR = 2.57) or obese (OR = 5.30), and a lower weight-specific quality of life (OR = 0.97 and OR = 0.95, respectively) than healthy-weight youth. Obese youth have lower healthy lifestyle priorities (OR = 0.75) and are less likely to be physically active (OR = 0.79) and eat breakfast (OR = 0.47) than healthy-weight youth. Additionally, overweight and obese youth are more likely to engage in weight control behaviors (OR = 5.19 and OR = 8.88, respectively) and restrained eating than healthy-weight youth. All the aforementioned results had a p-value of <0.05, which was considered statistically significant. The association between these factors and overweight or obesity remained significant after controlling for age, sex, race/ethnicity, and country. In conclusion, obesity was associated with a range of psychosocial, behavioral, and socio-environmental risk factors in both countries. Our findings support the need for multifactorial approaches when developing interventions to address the growing problem of obesity among youth in the US and Mexico.
Although the benefits of physical activity (PA) on to prevent and manage non-communicable diseases are well known, strategies to help increase the levels of PA among different populations are ...limited. Exercise-referral schemes have emerged as one effective approach to promote PA; however, there is uncertainty about the feasibility and effectiveness of these schemes in settings outside high-income countries. This study will examine the effectiveness of a scheme to refer hypertensive patients identified in Primary Health Care facilities (PHCU) of the Mexican social security institution to a group PA program offered in the same institution.
We will describe the methods of a cluster randomized trial study designed to evaluate the effectiveness of an exercise referral scheme to increasing physical activity in hypertensive patients compared to a non-referral scheme. Four PHCU were selected for the study; the PHCU will take part as the unit of randomization and sedentary hypertensive patients as the unit of assessment. 2 PHCU of control group (GC) will provide information to hypertensive patients about physical activity benefits and ways to increase it safely. 2 PHCU of intervention group (IG) will refer patients to sports facilities at the same institution, to follow a group-based PA program developed to increase the PA levels with a designed based on the Transtheoretical Model and Social Cognitive Theory. To evaluate the effects of the intervention as well as short-term maintenance of the intervention's effects, PA will be assessed at baseline, at 24 and 32 weeks of follow-up.The main outcome will be the difference before and after intervention in the percentage of participants meeting recommended levels of PA between and within intervention and control groups. PA will be measured through self-report and with objective measure by accelerometer.
This study will allow us to evaluate a multidisciplinary effort to link the primary care and community-based areas of the same health care system. Our findings will provide important information about the feasibility and effectiveness of an exercise-referral scheme and will be useful for decision-making about the implementation of strategies for increasing PA among hypertensive and other clinical populations in Mexico and Latin America.

To establish how health care service utilization patterns are associated with health-related quality of life (HRQL) perception in older adults.
A cross-sectional study in adults aged 60 years or more ...was conducted in a random sample of 1150 beneficiaries of the Mexican Social Security Institute (IMSS) in Mexico City during 2003. Health care services utilization was categorized as preventive or curative, which generated six usage profiles. HRQL was measured by means of the SF-36 questionnaire. Analyses of variance and multiple linear regressions were conducted to evaluate the relationship between health care services utilization and HRQL.
The use of preventive and curative services has a positive association with HRQL levels. Usage profiles with a prevalence of preventive services have a stronger positive association with HRQL scales.
This study suggests a positive association between use patterns for primarily preventive health care services and a better HRQL perception among older adults.
To prospectively examine the extent to which mealtime habits influences the risk of weight gain and obesity in Mexican adults.
We performed a prospective cohort study. The Mealtime Habits Quality ...(MHQ) scale was used for assessing participants' MHQ; the outcomes of interest were gain ≥5 % of body weight, developing overweight/obesity and abdominal obesity, after 7 years of follow-up. In order to estimate the independent effect of MHQ on anthropometric indicators, generalized linear models were computed to obtain adjusted relative risks (95 % CI).
The state of Morelos, Mexico.
Mexican adults (n 837) aged 18-70 years participating in a cohort study.
Compared with participants classified in the higher MHQ category, individuals in the middle and lower MHQ groups had a 4·1 (2·5, 6·7) and 6·2 (3·9, 9·7) fold greater risk of gain ≥5 % of body weight, respectively; 6·6 (2·8, 15·5) and 8·6 (3·7, 19·8) fold greater risk of becoming overweight/obese, respectively; and 3·8 (2·0, 7·3) and 5·3 (2·8, 9·8) fold greater risk of developing abdominal obesity, respectively.
This study provides evidence about the influence of a set of mealtime habits on obesity indicators, showing that greater adherence to unadvisable mealtime habits increases the risk of developing unhealthy anthropometric indicators. Since the meal is one of the most important sources of food intake, and consequently weight status, the MHQ scale can be a useful population tool to predict weight gain and obesity.
