The Associations Between Breastfeeding Duration and Body Dissatisfaction, Ethnicity, and Obesity Among Mexican Women, a Cross-Sectional Study, ENSANUT 2012.

ABSTRACT: Introduction: Body image dissatisfaction (BID) has been inversely associated with breastfeeding initiation particularly among women with obesity. However, less is known on BID and the association with maintaining breastfeeding in Mexico, where breastfeeding rate is decreasing across ethnic subgroups. Therefore, we explore this gap of knowledge in diverse ethnic subgroups across levels of maternal weight status. Methods: Data were derived from the Mexican National Health and Nutrition Survey (Encuesta Nacional de Salud y Nutrición [ENSANUT] 2012), and 10,466 women aged 20-49 years were included. Breastfeeding (<6 months versus ?6 months) of the last child, BID (Stunkard Figure Rating Scale), anthropometric (body mass index, BMI), sociodemographics, and biological variables were collected. Crude and adjusted target associations and effect modifiers were assessed using weighted-logistic regression models. Results: Overall, 72.4% of ever breastfeeding mothers breastfed a minimum of 6 months, 22% were indigenous, 74% were dissatisfied with their body image (BID >0), and 37% had obesity (BMI ?30?kg/m²). In the multivariable analysis, for each one-unit increase in the BID score, the adjusted odds of breastfeeding (?6 months) decreased by 6% (odds ratio [OR]?=?0.94, 95% confidence interval [CI]: 0.89-0.99). After stratifications, only among women with obesity, a greater BID score was associated with lower odds of breastfeeding duration by 24% (OR?=?0.76, 95% CI: 0.64-0.89) in indigenous and by 10% (OR?=?0.90, 95% CI: 0.82-0.98) in non-indigenous women. Conclusions: Mexican women with a higher BID score reported lower odds of breastfeeding duration (?6 months). Body image concerns should be integrated into a health promotion curriculum to mitigate their negative effect particularly in certain segments of the populations, such as women with obesity and among indigenous women.

Project description:Background: Additional metabolic indicators ought to be combined as outcome variables when exploring the impact of breastfeeding on obesity risk. Given the role of a healthy lifestyle in reducing obesity, we aimed to assess the effect of breastfeeding duration on different obesity phenotypes according to metabolic status in children and adolescents, and to explore the offsetting effect of healthy lifestyle factors on the associations between breastfeeding duration and obesity phenotypes. Methods: A total of 8208 eligible children and adolescents aged 7-18 years were recruited from a Chinese national cross-sectional study conducted in 2013. Anthropometric indicators were measured in the survey sites, metabolic indicators were tested from fasting blood samples, and breastfeeding duration and sociodemographic factors were collected by questionnaires. According to anthropometric and metabolic indicators, obesity phenotypes were divided into metabolic healthy normal weight (MHNW), metabolic unhealthy normal weight (MUNW), metabolic healthy obesity (MHO), and metabolic unhealthy obesity (MUO). Four common obesity risk factors (dietary consumption, physical activity, screen time, and sleep duration) were used to construct a healthy lifestyle score. Scores on the lifestyle index ranged from 0 to 4 and were further divided into unfavorable lifestyles (zero or one healthy lifestyle factor), intermediate lifestyles (two healthy lifestyle factors), and favorable lifestyle (three or four healthy lifestyle factors). Multinomial logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (95% CI) for the associations between breastfeeding duration and obesity phenotypes. Furthermore, the interaction terms of breastfeeding duration and each healthy lifestyle category were tested to explore the offsetting effect of lifestyle factors. Results: The prevalence of obesity among Chinese children and adolescents aged 7-18 years was 11.0%. Among the children and adolescents with obesity, the prevalence of MHO and MUO was 41.0% and 59.0%, respectively. Compared to the children and adolescents who were breastfed for 6-11 months, prolonged breastfeeding (≥12 months) increased the risks of MUNW (OR = 1.35, 95% CI: 1.19-1.52), MHO (OR = 1.61, 95% CI: 1.27-2.05), and MUO (OR = 1.46, 95% CI: 1.20-1.76). When stratified by healthy lifestyle category, there was a typical dose-response relationship between duration of breastfeeding over 12 months and MUNW, MHO, and MUO, with an increased risk of a favorable lifestyle moved to an unfavorable lifestyle. Conclusions: Prolonged breastfeeding (≥12 months) may be associated with increased risks of MUNW, MHO, and MUO, and the benefits of breastfeeding among children and adolescents may begin to wane around the age of 12 months. The increased risks may be largely offset by a favorable lifestyle.

Project description:BackgroundLifestyles such as unhealthy diets and the lack of physical activity have been contributed to the increased prevalence of obesity. In 2012, the world health organization published the first global recommendation for physical activity and health. People who do not meet at least 150 minutes of moderate-to-vigorous physical activity are considered to be physically inactive. The prevalence of physical inactivity worldwide is 31%, however there is insufficient data from prevalence and trends of physical inactivity in Mexican population. The purposes of this study are to describe the physical inactivity prevalence and recent trends in Mexican adults and to examine the association between physical inactivity with biologic and sociodemographic characteristics.MethodsRepresentative samples of 17,183 and 10,729 adults (aged 20 to 69 years) who participated in the National Health and Nutrition Survey (ENSANUT) in 2006 and 2012, respectively. Moderate-to-vigorous physical activity (MVPA) was assessed using the short form version of the International Physical Activity Questionnaire (IPAQ), which was administered in face-to-face interviews. Self-reported IPAQ MVPA levels were adjusted using an equation derived from a previous validation study. Participants were considered inactive if they engaged in <150-minutes/week of moderate physical activity or <75 minutes/week of vigorous physical activity according to WHO classification criteria.ResultsThe prevalence of physical inactivity was significantly higher in 2012 (19.4%, 95% CI: 18.1, 20.7) than in 2006 (13.4%, 95% CI: 12.5, 14.5). Adults in the obese category, 60-69 age group, and those in the highest socioeconomic status tertile were more likely to be physically inactive.ConclusionsThe proportion of the Mexican adult population who do not meet the minimum WHO physical activity criteria has increased by 6% points between 2006 and 2012. Given the increasing prevalence of obesity, the aging of the population, and the shift in socioeconomic status in Mexico, physical inactivity could continue to increase in the coming years unless effective public health interventions are implemented.
