Abstract

OBJECTIVE: To evaluate the effect of a Mindful Restaurant Eating intervention on weight management.

DESIGN: Randomized control trial.

SETTING: Greater metropolitan area of Austin, Texas.

PARTICIPANTS: Women (n = 35) 40-59 years old who eat out at least 3 times per week.

INTERVENTION: The intervention, using 6 weekly 2-hour, small group sessions, focused on reducing calorie and fat intake when eating out through education, behavior change strategies, and mindful eating meditations.

MAIN OUTCOME MEASURES: Weight, waist circumference, self-reported daily calorie and fat intake, self-reported calories and fat consumed when eating out, emotional eating, diet related self-efficacy, and barriers to weight management when eating out.

ANALYSIS: General linear models examined change from baseline to final endpoint to determine differences in outcomes between the intervention and control group.

RESULTS: Participants in the intervention group lost significantly more weight (P =.03), had lower average daily caloric (P = .002) and fat intake (P = .001), had increased diet-related self-efficacy (P = .02), and had fewer barriers to weight management when eating out (P = .001).

CONCLUSIONS AND IMPLICATIONS: Mindful Restaurant Eating intervention was effective in promoting weight management in perimenopausal women.

Abstract

The Breastfeeding, Antiretrovirals, and Nutrition study evaluated the effect of daily consumption of lipid-based nutrient supplements (LNS) by 2121 lactating, HIV-infected mothers on the growth of their exclusively breast-fed, HIV-uninfected infants from 0 to 24 wk. The study had a 2 × 3 factorial design. Malawian mothers with CD4+ ≥250 cells/mm3, hemoglobin ≥70 g/L, and BMI ≥17 kg/m2 were randomized within 36 h of delivery to receive either no LNS or 140 g/d of LNS to meet lactation energy and protein needs, and mother-infant pairs were assigned to maternal antiretroviral drugs (ARV), infant ARV, or no ARV. Sex-stratified, longitudinal, random effects models were used to estimate the effect of the 6 study arms on infant weight, length, and BMI. Logistic regression models were used to calculate the odds of growth faltering [decline in weight-for-age Z-score (WAZ) or length-for-age Z-score (LAZ) >0.67] using the control arm as the reference. Although some differences between study arms emerged with increasing infant age in boys, there were no consistent effects of the maternal supplement across the 3 growth outcomes in longitudinal models. At the ages where differences were observed, the effects on weight and BMI were quite small (≤200 g and ≤0.4 kg/m2) and unlikely to be of clinical importance. Overall, 21 and 34% of infants faltered in WAZ and LAZ, respectively. Maternal supplementation did not reduce the odds of infant weight or length faltering from 0 to 24 wk in any arm. These results indicate that blanket supplementation of HIV-infected lactating women may have little impact on infant growth.
