Fatty and lean red meat consumption: different effects on Chinese abdominal obesity (628.1)

Abstract

This study prospectively investigates the association between red meat (RM) and subtypes intakes on the risk of abdominal obesity in Chinese adults aged 18 to 75 year. Data are from the China Health and Nutrition Survey (CHNS) consisting of 47,785 observations from 16,822 adults from 1993 to 2011. RM intake was assessed with 3 d 24‐h dietary recalls. Abdominal obesity was defined as a waist circumference (WC) 蠅85 cm for men and 蠅80 cm for women. Multilevel mixed‐effect regression models showed that men had an increase in 0.74 cm (95% CI: 0.39, 1.09, p<0.001), 0.59 cm (95% CI: 0.24, 0. 95, p=0.01) of WC from higher intake of total RM and fatty RM but not lean RM intake [0.14 cm (95% CI: ‐0.39, 0.66, p=0.92)] in the top vs. the bottom quartile when adjusted for confounders of diet and activity and socioeconomic factors. In contrast, after additional adjustment for baseline WC, the odds ratios of abdominal obesity in men were deattentuated for total RM [1.25 (95% CI: 1.06, 1.47, p=0.01)] and fatty RM [1.22 (95% CI: 1.03, 1.44, p=0.14)] but still not affected by lean RM [0.95 (95% CI: 0.75, 1.22, p=0.74)]. No significant effects were seen in women’s WC and abdominal obesity. The gender effects and differential effects of fatty vs. lean RM warrant further study.Grant Funding Source: Supported by NIH R01‐HD30880 and R01‐HD38700 and the Fogarty International Center
