Vitamin D deficiency and hyperparathyroidism in relation to ethnicity: a cross-sectional survey in healthy adults.

BACKGROUND: The study of vitamin D status at population level gained relevance since vitamin D deficiency was recently suggested to trigger chronic disease. AIM OF THE STUDY: We aimed to describe vitamin D status, its association with bone and mineral metabolism and risk factors for deficiency in adults over 40 years in Belgium. METHODS: We conducted a cross-sectional survey in a stratified random sample of 401 subjects aged between 40 and 60 years living in Brussels, and drawn from 4 different ethnic backgrounds: autochthonous Belgian, Moroccan, Turkish and Congolese. 25-Hydroxyvitamin D (25OHD), parathyroid hormone (PTH), osteocalcin, C-telopeptide and bone mineral density was measured. RESULTS: Three-hundred and six subjects (77%) showed 25OHD concentrations below 50 nmol/l,135 (34%) below 25 nmol/l and 18 (5%) below 12.5 nmol/l. The proportion of subjects with vitamin D deficiency was four times greater amongst those of Moroccan or Turkish descent compared with those of Congolese or Belgian descent. Moroccan subjects showed a significant higher PTH and bone marker concentrations compared to Belgian. Ethnicity, season and sex were independently associated with vitamin D deficiency in multivariate analysis. CONCLUSION: The prevalence of vitamin D deficiency is very high amongst the adult population of Brussels but immigrants are at greater risk. Given the established link between population health and adequate vitamin D status, a policy of vitamin D supplementation should be considered in these risk groups.

Healthy food and nutrient index and all cause mortality.

OBJECTIVES: To develop a Healthy Food and Nutrient Index (HFNI) and to relate this index to the all cause mortality observed in two Belgian communities. DESIGN: Using the 10-years follow-up mortality data from the 'Belgian Inter-university Research on Nutrition and Health' (BIRNH) study, the association of a Healthy Food and Nutrient Index (HFNI) and all cause mortality was investigated in 5,887 men and 5,306 women aged 25-74 years. The HFNI was developed on the basis of the national dietary guidelines. The higher the index the more the diet can be considered to conform to the recommendations. RESULTS: After adjustment for classic all cause mortality risk factors, HFNI was related with mortality for men. A decrease in risk of death is noted from Quartile 1 to Quartile 4. Among the women, HFNI remains non-significant. The ability of the models (with and without HFNI) to discriminate the living and the dead was evaluated by constructing a receiver operating characteristic (ROC) curves. For all models, areas under the Roc curves were between 0.80 and 0.85 indicating that all models discriminate well alive subjects of deceased. However, comparison of the areas under the ROC curves of the models without HFNI with the ROC areas of the models with HFNI showed no improvement in our ability to discriminate between the living and the dead. CONCLUSION: Although it is not demonstrated in our study, we think that the overall approach offers an opportunity to improve our understanding of the role of diet in the risks of morbidity or mortality associated with the overall dietary pattern rather than some individual foods and nutrients.

Decoding emotional facial expressions in depressed and anorexic patients.

BACKGROUND: Several studies suggest the existence of impairments in the decoding of emotional facial expressions in various psychopathological conditions. This study investigates the recognition of emotional facial expressions (EFE) in young depressed patients and compares it to patients with eating disorders and control subjects. METHODS: 21 hospitalized female adolescents with major depression, 36 hospitalized female adolescents with eating disorders and 32 female control subjects were investigated with a set of emotional facial stimuli [Hess, U., Blairy, S., 1995. Set of Emotional Facial Stimuli, Department of Psychology, University of Quebec at Montréal, Montréal, Canada]. RESULTS: No significant differences were found between anorexic patients and controls in EFE decoding. Significant results were observed for depressed patients: they were less accurate in EFE decoding compared to anorexic patients and controls for the emotion of anger. LIMITATIONS: Previous studies on EFE decoding in depression and eating disorders used different facial stimuli or methodology. Furthermore, our study concerns only female subjects. These limitations could explain some discrepant result. CONCLUSIONS: The present results support the existence of impairments in the decoding of facial expressions in young female patients suffering from major depression.

Role of physicians in preventing accidents in the home involving children under 15 years in the French-speaking community of Belgium.

OBJECTIVES: To measure GPs' and paediatricians' expectations, attitudes, priorities and demands in the area of promoting safety and preventing accidents in the home involving children under 15 years of age. METHODS: A phone survey of a random sample of GPs and paediatricians in the French-speaking community of Belgium (Wallonia and Brussels) conducted in the course of September and October 2000. RESULTS: Close to two-thirds of the physicians surveyed stated that they had been contacted at least once in the 2 weeks preceding the survey to handle an injury. Of the physicians, 80% mention accident prevention after a childhood injury, but only 46% mention it during a routine consultation (whatever the reason of the latter may be). The main obstacles to mentioning prevention during routine consultation put forward by the interviewees are: 1) reasons for consultations that do not permit such an approach (79%); 2) the fact that injuries are not priorities for them (66%); 3) the lack of interesting materials to provide the subject with documentation (63%); 4) the unsuitability of the place where the contact occurs for such discussion, given the time required (56%); 5) insufficient information on the subject (41%); and 6) the patient's lack of interest (39%). An overwhelming majority (98%) nevertheless feel that they have a role to play in preventing children's accidents in the home, with 72.5% seeing this as informative (recommendation on safety rules). More than two-thirds of the respondents feel that they have enough requisite information to play such a role. Those who declare that they have not enough information (34%) proposed some priority subjects about which they would like to find information or additional information to be more effective in preventing accidents. The information needs mentioned most frequently were a systematic review of the risks, of the effective prevention strategies and epidemiological data. CONCLUSIONS: The present study clearly reveals the interest of physicians for accident prevention and puts forward the current obstacles to offering prevention advice during routine consultation. The obstacles mentioned are fairly comparable to those mentioned in other studies, namely, because the reason for the visit does not give such an opening, the lack of appropriate materials and information, the lack of time, the patient's lack of interest, the fact that the issue is not a priority, etc. The problem of lack of priority for certain practitioners underlines the importance of making accident mortality and morbidity statistics available to doctors in order to improve their perception of the magnitude of the problem. The lack of interesting education materials and useful information seems to be a major reason for their failure to carry out such prevention work successfully. These factors should thus be taken into account when developing any policy and/or programme aimed at 'using' GPs and paediatricians in the prevention strategies that are adopted.
