Abstract
BackgroundThe objetive in this study is to determine the relationship between dietary patterns, BMI, type 2 diabetes mellitus family history (T2DMFH) and some lifestyle variables such as smoking and skipping breakfast in a Mexican adolescent population.MethodsCross-sectional, observational, analytical study.Subjetcts: 14-16 years old male and female adolescents (n 373). A previously validated food frequency questionnaire (FFQ) was used and dietary patterns were derived using principal component analysis (PCA). Scores for dietary patterns were categorized by tertiles.ResultsThree major dietary patterns that explained 47 % of variance were found: westernized, high in protein/fat and prudent pattern. Subjects at the highest tertile of prudent pattern had lower BMI. And was also associated with less T2DMFH and less smoking habit when compared with the lowest tertile. We found a positive correlation between BMI and high scores for westernized and high in protein/fat patternConclusionsDietary patterns of adolescents are a public health concern because there is a direct association between inadequate diet at this early age and obesity
Highlights
The objetive in this study is to determine the relationship between dietary patterns, body mass index (BMI), type 2 diabetes mellitus family history (T2DMFH) and some lifestyle variables such as smoking and skipping breakfast in a Mexican adolescent population
Dietary patterns emerged as an alternative method for the study of the relationship between diet and chronic diseases; traditionally, nutritional epidemiology studies are focused on some diseases and their relation to specifics nutrients or foods [1, 2], people consume food combinations that contain a mixture of nutrients
This study aims to understand the dietary patterns of adolescents and their relation to different lifestyle variables and body mass index (BMI)
Summary
The objetive in this study is to determine the relationship between dietary patterns, BMI, type 2 diabetes mellitus family history (T2DMFH) and some lifestyle variables such as smoking and skipping breakfast in a Mexican adolescent population. Dietary patterns analysis focuses on the study of the diet as a whole concept. It has been suggested that unhealthy dietary patterns are present from early stages of life. Despite being widely recognized the importance of establishing healthy eating behaviors early in life, few investigations have been made on dietary patterns in adolescents [7]. This study aims to understand the dietary patterns of adolescents and their relation to different lifestyle variables and body mass index (BMI)
