AI Article Synopsis

  • The study examined the link between adherence to French dietary guidelines (PNNS-GS2) and the risk of developing type 2 diabetes (T2D) in a cohort of 71,450 women, with an average age of around 53 years.
  • Results showed that better adherence to these dietary guidelines was associated with a reduced risk of T2D, indicating that diet plays a significant role in diabetes prevention.
  • The research also found that this protective effect was primarily mediated by body weight, with more than half of the relationship explained through body mass index (BMI) and waist-hip ratio (WHR).

Article Abstract

Objective: Obesity and type 2 diabetes (T2D) have been associated with low adherence to the 2017 French food-based dietary guidelines, as assessed by the Programme National Nutrition Santé - guidelines score 2 (PNNS-GS2). Whether the association between T2D and PNNS-GS2 is direct or mediated by obesity has been little investigated.

Research Methods: The study included 71,450 women from the E3N-EPIC cohort, mean age of 52.9 y (SD 6.7). The simplified PNNS-GS2 was derived via food history questionnaire. Multivariable Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of T2D. Causal mediation analyses were used to decompose the total effect of sPNNS-GS2 on T2D into a direct effect and indirect effect mediated by body mass index (BMI) or the waist-hip ratio (WHR).

Results: During a mean follow-up of 19 y, 3679 incident T2D cases were identified and validated. There was a linear association between adherence to sPNNS-GS2 and T2D (P-nonlinearity = 0.92). In the fully adjusted model, each 1-SD increase in the sPNNS-GS2 was associated with a lower T2D risk [HR (95% CI), 0.92 (0.89, 0.95)]. The overall associations were mainly explained by sPNNS-GS2-associated excess weight, with BMI and WHR mediating 52% and 58% of the associations, respectively.

Conclusions: Higher adherence to French food-based dietary guidelines was associated with a lower risk of T2D in women, and a significant portion of this effect could be attributed to excess weight measured by BMI or WHR. This finding helps better understand the mechanisms underlying the diet-T2D association.

Changes in Grocery Shopping Behavior among Low-Income Households during the COVID-19 Pandemic.

Public Health Nutr

January 2025

Department of Nutrition and Food Studies, Steinhardt School of Culture, Education, and Human Development, New York University, 411 Lafayette St, 5th floor, New York, NY 10003.

Objective: The Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot (OPP) authorized the use of SNAP benefits online in Maryland in May 2020. We assessed shopping behavior and intentions associated with uptake and intended future use of online grocery shopping during and after COVID-19 among SNAP-eligible households.

Design: In this mixed-methods study, participants completed a survey on online grocery shopping, and a purposefully sampled subset participated in focus groups or in-depth interviews between November 2020 and March 2021.

Objective: Early education and care (ECEC) is part of the everyday life of most children in developed economies presenting exceptional opportunity to support nutrition and ongoing food preferences. Yet, the degree to which such opportunity is captured in policy-driven assessment and quality ratings of ECEC services is unknown.

Design: Abductive thematic analysis was conducted, guided by key domains of knowledge in nutrition literature and examining identified themes within these domains.

Background: Use of health applications (apps) to support healthy lifestyles has intensified. Different app features may support effectiveness, including gamification defined as the use of game elements in a non-game situation. Whether health apps with gamification can impact behaviour change and cardiometabolic risk factors remains unknown.

Background: During lactation, maternal requirements for many nutrients increase due to the physiological demands of breast milk production, reflected in dietary recommendations. BMI is negatively associated with dietary quality postpartum, and 40% of women in Norway have pre-pregnancy overweight and obesity. Currently, there is limited data on dietary intake among lactating women in Norway and whether they meet nutritional requirements.

Background: Incorporating scratch-cooked, organic, and locally grown foods into school meal programs can enhance meal quality and support local food systems.

Methods: 430 California school food authorities were surveyed to (1) evaluate their use of scratch-cooked, organic, and locally grown foods in their programs; (2) identify demographic and operational characteristics related to this use; and (3) analyze the relationship between serving more of these foods and perceived barriers to student meal participation. Poisson and logistic regression models, adjusted for SFAs' demographic characteristics, were used.
