BACKGROUND Dietary Guidelines are considered as a useful tool for the promotion of healthy dietary behaviors. In Iran, despite the development of the latest National Food-Based Dietary Guidelines, in 2006, it has not been introduced at the community level yet. The present study aims to evaluate the effectiveness of an intervention program to promote Iran's Food-Based Dietary Guidelines (IFBDGs)...

BACKGROUND Maternal diet is known to impact pregnancy outcome. Following a low glycemic index (GI) diet during pregnancy has been shown to improve maternal glycemia and reduce infant birthweight and may be associated with a higher fibre intake. We assessed the impact of a low GI dietary intervention on maternal GI, nutritional intake and gestational weight gain (GWG) during pregnancy. Complianc...

Background: Stomach cancer is one of the five most common cancers in Iran. This study examined the effectiveness of a mobile telephone short-message service (SMS) based-education intervention using Health Belief Model (HBM) variables in improving dietary behavior in terms of stomach cancer prevention among a sample of Iranian female college students. Materials and Methods: In this quasi-experim...

1. Intervention trials in free-living populations have shown relatively small reductions in risk factors for cardiovascular disease, including lipid levels, and have led some to question whether diet is an effective treatment for hyperlipidaemia. However, behaviour change is a complex process and it is possible that standard intervention methods fail to motivate people sufficiently to comply wi...

BACKGROUND Although there are many effective lifestyle interventions for type 2 diabetes (T2DM) prevention, insight into effective intervention pathways, especially of long-term interventions, is often lacking. This study aims to provide insight into the effective intervention pathways of the SLIMMER diabetes prevention intervention using mediation analyses. METHODS In total, 240 participants...

BACKGROUND Preclinical and observational studies suggest a relationship between dietary fat intake and breast cancer, but the association remains controversial. We carried out a randomized, prospective, multicenter clinical trial to test the effect of a dietary intervention designed to reduce fat intake in women with resected, early-stage breast cancer receiving conventional cancer management. ...

OBJECTIVE In the past decade, there has been no systematic review of the evidence for maintenance of physical activity and/or dietary behavior change following intervention (follow-up). This systematic review addressed three questions: 1) How frequently do trials report on maintenance of behavior change? 2) How frequently do interventions achieve maintenance of behavior change? 3) What sample, ...

BACKGROUND The Polyp Prevention Trial (PPT) was a multicenter randomized clinical trial designed to determine the effects of a high-fiber (4.30 g/MJ), high-fruit-and-vegetable (0.84 servings/MJ), low-fat (20% of energy from fat) diet on the recurrence of adenomatous polyps in the large bowel. OBJECTIVE Our goal was to determine whether the PPT intervention plan could effect change in 3 dietar...

OBJECTIVE The present study aimed to compare the effects of a general dietary intervention and an intervention with low glycaemic load (GL) on glycaemic control, blood lipid metabolism and pregnancy outcomes in women with gestational diabetes mellitus. DESIGN Participants were randomly assigned to two groups, receiving either an individualized general dietary intervention (Control group) or a...
