ABSTRACT

UNLABELLED: Prevention of fractures is a considerable public health challenge. In a population-based cohort of French elderly people, a diet closer to a Mediterranean type had a borderline significant deleterious effect on the risk of fractures, in part linked to a low consumption of dairy products and a high consumption of fruits. INTRODUCTION: Higher adherence to the Mediterranean diet (MeDi) is linked to a lower risk of several chronic diseases, but its association with the risk of fractures is unclear. Our aim was to investigate the association between MeDi adherence and the risk of fractures in older persons. METHODS: The sample consisted of 1,482 individuals aged 67 years or older, from Bordeaux, France, included in the Three-City Study in 2001-2002. Occurrences of hip, vertebral and wrist fractures were self-reported every 2 years over 8 years, and 155 incident fractures were recorded. Adherence to the MeDi was evaluated at baseline by a MeDi score, on a 10-point scale based on a food frequency questionnaire and a 24-h recall. Multivariate Cox regression tests were performed to estimate the risk of fractures according to MeDi adherence. RESULTS: Higher MeDi adherence was associated with a non-significant increased risk of fractures at any site (hazard ratio [HR] per 1-point increase of MeDi score = 1.10, P = 0.08) in fully adjusted model. Among MeDi components, higher fruits consumption (>2 servings/day) was significantly associated with an increased risk of hip fractures (HR = 1.95, P = 0.04), while low intake of dairy products was associated with a doubled risk of wrist fractures (HR = 2.03, P = 0.007). An inverse U-shaped association between alcohol intake and risk of total fracture was observed (HR high vs. moderate = 0.61, P for trend = 0.03). CONCLUSIONS: Greater MeDi adherence was not associated with a decreased risk of fractures in French older persons. The widely recognized beneficial effects of the MeDi do not seem to apply to bone health in these people.

ABSTRACT

UNLABELLED: We investigated the association between nutrient patterns and risk of fractures in 1,482 older subjects. Patterns associated with higher intakes of Ca, P, vitamin B12, proteins and unsaturated fats, and moderate alcohol intake, provided by diets rich in dairies and charcuteries, were related to a lower risk of wrist and hip fractures. INTRODUCTION: The purpose of this study was to investigate the relationship between patterns of nutrient intake and the risk of fractures in older subjects. METHODS: Among 1,482 participants from the Bordeaux sample of the Three-City (3C) Study who completed a 24-h dietary recall and a food frequency questionnaire, we examined the association between patterns of nutrient intake derived from principal component analysis and 8-year incidence of self-reported fractures of the hip, the wrist, and the vertebrae. RESULTS: A "nutrient-dense" pattern rich in Ca and P, iron, vitamins B including B12, vitamins C and E, alcohol, proteins, and unsaturated fats, and characterized by a higher consumption of fruits and vegetables, meats and fish, cheese and milk, charcuteries, cereals, rice, pasta, and potatoes, was associated with a 19% (95% CI 2-34%, P=0.03) lower risk of wrist fractures. The same pattern was associated with a 14% (95% CI 2-25%) lower risk of fractures at any site. A "south-western French" pattern rich in Ca, P, vitamins D and B12, retinol, alcohol, proteins, and fats-including unsaturated fats; poor in vitamins C, E, and K, carotenes, folates, and fibers; and related to a higher consumption of cheese, milk, and charcuterie and a lower consumption of fruits and vegetables was related to a 33% lower risk of hip fractures (95% CI 3-39%, P=0.03). CONCLUSIONS: Higher intakes of Ca, P, vitamin B12, proteins, and unsaturated fats and moderate alcohol, provided by dietary patterns rich in cheese, milk, and charcuteries, were related to a lower risk of wrist and hip fractures in our cohort.

ABSTRACT

BACKGROUND/OBJECTIVES: The ELPAS (Etude Longitudinale Prospective Alimentation et Santé) study was an 8-month randomized controlled dietary modification trial designed to test the hypothesis that family dietary coaching would improve nutritional intakes and weight control in 2026 free-living children and parents. It resulted in significant nutritional changes, with beneficial effects on body mass index in adults. In these ancillary analyses, we investigated dietary changes throughout the intervention. SUBJECTS/METHODS: Before the study, modeling analyses were carried out on the French Association Sucre Produits Sucrés Consommation et Communication (ASPCC) food-consumption database to identify the most efficient dietary intervention strategy. During the study, all participants performed monthly three nonconsecutive 24-h dietary recalls: this allowed for measuring changes in the number of servings per day and serving size for each targeted food category throughout the intervention. RESULTS: Modeling analyses showed that targeting only the 10 main foods contributing to fat and carbohydrate intakes did not allow for reaching the ELPAS nutritional goals. As a result, it was decided to target more foods and to propose several types of dietary advice (such as change in serving size, change in cooking method, food substitution). This strategy led to many appropriate dietary changes during the intervention, but only a few of them reached significance. The mean number of servings per day was indeed significantly modified for only 7% of the targeted food categories in children and 17% in parents. The mean serving size was modified for only 12% of targeted food categories in children and 9% in parents. CONCLUSIONS: The cumulative effect of small dietary changes may induce significant nutritional improvements, with limited burden for populations.
