Scale for assessing the quality of Mexican adults' mealtime habits

To construct a scale for assessing the quality of mealtime habits in a sample of urban Mexican adults, computing the contribution of a set of advisable and unadvisable mealtime habits. Material and Methods. We performed an exploratory factor analysis among 7 472 adults participating in the baseline assessment of the Health Workers Cohort Study, to assess the mealtime habits quality. Likelihood ratio test for difference of two probabilities and test for the difference of two means were used to identify differences between low and high categories of the Mealtime Habits Quality Scale (MHQS) across variables of interest. Results. Participants with the top quality of mealtime habits showed lower rates of overweight, obesity, abdominal obesity, and elevated body fat. They were also more adherent to a prudent dietary pattern than a western dietary pattern, and consumed more fruits and vegetables. Conclusions. Anthropometric and dietary variables differed across MHQS categories. However, further validation of the scale, and assessment of their ability to predict weight gain or related diseases are needed, using prospective and intervention studies

Reference values for areal bone mineral density among a healthy Mexican population

Objective. Compare the influence of ethnicity in the prevalence of osteopenia and osteoporosis in various Mexican populations using two normal dual X-ray absorptiometry (DXA) reference databases: manufacturer¿s incorporating US Hispanic population and a normal mestizo Mexican population. Material and Methods. MMP included 9 946 subjects participating in an ongoing long-term cohort study focusing on lifestyle and chronic diseases, of which 6 487 MMP males and females aged 7 to 80 years were the normal subjects used to determine bone density T- and Z-scores, following WHO criteria, and peak bone mass values. Abnormal bone mass density values estimated by the manufacturer's and peak bone mass reference values were compared. Results and Conclusions. Our results show that by using the manufacturer´s T-score values in the mestizo Mexican population we are underestimating the number of abnormal bone mass BMD populations
