Inverse association of farm milk consumption with asthma and allergy in rural and suburban populations across Europe.

BACKGROUND: Dietary interventions as a means for atopy prevention attract great interest. Some studies in rural environments claimed an inverse association between consumption of farm-produced dairy products and the prevalence of allergic diseases, but current evidence is controversial. OBJECTIVE: To investigate whether consumption of farm-produced products is associated with a lower prevalence of asthma and allergy when compared with shop-purchased products. METHODS: Cross sectional multi-centre study (PARSIFAL) including 14,893 children aged 5-13 years from five European countries (2823 from farm families and 4606 attending Steiner Schools as well as 5440 farm reference and 2024 Steiner reference children). A detailed questionnaire including a dietary component was completed and allergen-specific IgE was measured in serum. RESULTS: Farm milk consumption ever in life showed a statistically significant inverse association with asthma: covariate adjusted odds ratio (aOR) 0.74 [95% confidence interval (CI) 0.61-0.88], rhinoconjunctivitis: aOR 0.56 (0.43-0.73) and sensitization to pollen and the food mix fx5 (cut-off level of >or=3.5 kU/L): aOR 0.67 (0.47-0.96) and aOR 0.42 (0.19-0.92), respectively, and sensitization to horse dander: aOR 0.50 (95% CI 0.28-0.87). The associations were observed in all four subpopulations and independent of farm-related co-exposures. Other farm-produced products were not independently related to any allergy-related health outcome. CONCLUSION: Our results indicate that consumption of farm milk may offer protection against asthma and allergy. A deepened understanding of the relevant protective components of farm milk and a better insight into the biological mechanisms underlying this association are warranted as a basis for the development of a safe product for prevention.

Survey on the occurrence of Brachyspira species and Lawsonia intracellularis in children living on pig farms.

The occurrence of Brachyspira species and Lawsonia intracellularis was investigated by PCR analyses of faeces from 60 children living on European pig farms. In addition, 60 other children were included as controls. Two samples were positive for B. aalborgi but B. pilosicoli and L. intracellularis were not demonstrated.

Individual assessment of intake of energy, nutrients and water in 54 elderly multidiseased nursing-home residents.

PURPOSE: Examination of the individual intake of energy, nutrients and water in clinically stable multidiseased nursing-home residents. METHODS: Comprehensive clinical assessment of 54 elderly nursing-home residents (80 +/- 10 years, mean +/- SD). The intake of food and beverages was measured by the weighed food intake method during five consecutive week days followed by computerized transformation to energy, 21 different nutrients, dietary fiber, alcohol and water. The resting energy expenditure was determined by indirect calorimetry. RESULTS: There was at least 2-3-fold, variation in intake of energy, nutrients and water, present also when expressed per kg body weight. For some micronutrients the relative intake variation was more than 8-fold. The results are compared with the present swedish recommended dietary allowances as well as with seven other studies of dietary intake in elderly using the weighed food intake method. The residents had on average 14.1 (range 6-31) different current clinical problems and were treated with a mean of 9.5 different drugs. The nursing staff spent 40 % of the total daytime working hours (7 am to 7 pm) on nutrition related issues. CONCLUSIONS: The nursing-home residents exhibited a large interindividual heterogeneity regarding intake of energy, nutrients and water. More emphasis should be given to individualized nutrition assessment in clinical geriatric care as a more solid base for nutrition treatment programmes integrated with the regular medical management and evaluation.
