Epidemiologic evidence suggest that read meat intake(RMI) may be associated with higher risk of obesity and its related chronic diseases, but studies evaluating body composition are scarce. The objective of this cross-sectional study was to examine the association between RMI and body fatness (BF) in a sample of 175 Mexican women.
The study included women who assisted to 'Centro Meneses' located in Mexico City between January 2013 and December 2018. Measured weight, height, waist circumference(WC), physical activity, sociodemographic variables, body mass index (BMI) and body composition were obtained at the first visit. Body fat percent (BFP) was assessed via bioelectrical impedance analysis (InBody 270). All measures were assessed by trained staff. Dietary intake data were collected through a multiple-step 24-hour dietary recall (24H-DR). The different meats and meat products were grouped into the following: red meat, poultry, seafood and other meat products. Red meat was the sum of beef, pork, lamb, veal and game. The American Institute for Cancer Research guidelines were considered to evaluate the adherence to dietary recommendation for RMI (<18 ounces/week).The association between BF and recommendation adherence for RMI was investigated by multiple linear regression controlling for age, total energy intake, gravity, menopausal status, physical activity and other potential confounders.
Analysis showed a significant inverse association between the adherence to dietary recommendation for RMI and BFP (βs = -8.66, 95%CI -17.09, -0.2335, p<0.05) compared with not met recommendation (reference group), controlling for potencial confounders. Not associations were found between RMI and BMI or WC.
Among Mexican women, the RMI was associated with BPF, suggesting that consuming an appropriate amount of red meat is important to prevent and control obesity.
