OBJECTIVE:To study the relationships between body mass index (BMI) and different domains of disability in elderly subjects from the French 3C study. SETTING: Three cities in France: Bordeaux (South-West), Dijon (North-East) and Montpellier (South-East). DESIGN: Cross-sectional study. SUBJECTS: A sample of 8966 elderly community dwellers (age: 65-101 y). MEASUREMENTS: Main outcome measures: BMI, continence, basic and Instrumental Activities of Daily Living (ADL and IADL) and mobility. Adjustment variables: age, educational level, lifestyle, cognitive functioning, smoking and drinking history, depression, dyspnea, diabetes and indicator of cardiovascular disease. RESULTS: Obesity (BMIZ30 kg/m 2 ) was significantly associated with disability in each domain for women. The relationship tended to be linear for ADL and for continence; whereas for IADL, underweight women (BMI o21 kg/m 2 ) were also at higher risk of disability. In men, relationships were weaker since BMI was only associated with mobility restriction, with a higher risk for both underweight and obese subjects. CONCLUSION: These results are in favor of a strong association between obesity and the three domains of disability and incontinence. Weaker relationships between underweight and disability were observed. Results suggest that maintaining a BMI in the healthy range could contribute to independence in activities of daily living.

The objective of this study was to evaluate the efficacy of Daflon 500 mg (Dios)* in venous ulcers. A multicenter, double-blind, randomized, controlled versus placebo (Plac) trial was conducted, with stratification according to the size of ulcer (< or = 10 cm and > 10 cm). The protocol called for a two-month treatment with Dios (one tablet = 450 mg micronized purified Diosmin) or a placebo, two tablets/day, in addition to compression therapy. Evaluations were performed every fifteen days, from D0 to D60. The primary endpoint, in accordance with Alexander House group requirements were: percentage of patients with complete ulcer healing, ie, comparison between Dios and Plac group at D60, and comparison of survival curves in each group between D0 and D60 (log rank test). Secondary endpoints included ulcer surface area assessed by computerized planimetric measurements, qualitative evaluation of ulcers, and symptoms. The patients were 105 men and women ranging in age from eighteen to eighty-five years, with standard compression stocking, who were undergoing standardized local care of ulcer and had no significant arterial disease (ankle/arm systolic pressure index > 0.8). Fifty-three patients received Dios, and 52 received Plac. The 2 groups were well matched for age (m +/- 1 SD = seventy-one +/- eleven years), gender, ulcer size, and associated disorders. Among patients with ulcer size < or = 10 cm (Dios = 44, Plac = 47) a significantly larger number of patients had a complete ulcer healing at two months in the Dios group (n = 14) in comparison with the Plac group (n = 6) (32% vs 13%, P = 0.028) with a significantly shorter time duration of healing (P = 0.037). No difference was shown for the secondary criteria, except for sensation of heavy legs (P = 0.039) and a less atonic aspect of ulcer (P = 0.030) in favor of Dios. Among the 14 patients with ulcer size > 10 cm (Dios = 9, Plac = 5), subjected to a descriptive analysis only, no ulcer healed. This study showed that a two-month course of Daflon 500 mg at a daily dose of two tablets, in addition to conventional treatment, is of benefit in patients with venous ulcer < or = 10 cm by accelerating complete healing.

Background and Purpose-Gait dysfunction is an important cause of disability among the elderly and may be, in part, of vascular origin. We studied the association between carotid ultrasound parameters and measures of gait and balance in subjects 65 to 85 years of age who participated in the baseline phase of the Three-City Study in the Dijon center. Methods-The study population comprised 2572 noninstitutionalized individuals. Carotid plaques and common carotid artery intima-media thickness (CCA-IMT) were measured using ultrasonography. Gait and balance measures included walking speed and a modified version of the Tinetti scale. Results-Mean maximum walking speed (MWS) decreased with increasing CCA-IMT and number of plaques (PϽ10
