Background: Higher intake of fruits and vegetables appears to protect against inflammation, poor physical performance, and disability, but its relationship with muscle strength is unclear. We examined the association between total plasma carotenoids, an indicator of fruit and vegetable intake, and changes in muscle strength over a 6-year follow-up in the participants aged 65 years and older in the InCHIANTI study, a population-based study in Tuscany, Italy.

Methods: Plasma carotenoids were measured at enrollment (1998-2000).

Periodic vitamin A supplementation is a major intervention to reduce morbidity, mortality, and blindness among children in developing countries. The goal was to characterize the coverage of the Ethiopia national vitamin A program among preschool children and to identify risk factors for not receiving vitamin A. In the Ethiopia Demographic and Health Survey of 2005, among 4762 preschool children, aged 12-59 months, 46.

Objective: To determine whether vitamin A capsule programmes fail to reach children who are at higher risk of malnutrition and morbidity. Although it has been suggested that there are health disparities between children who are reached or not reached by these programmes, little quantitative work has been undertaken to characterize this relationship.

Study Design: As part of a national surveillance system, nutritional status and other factors were compared in 138,956 children, aged 12-59 months, who had and had not received vitamin A supplementation in urban slum areas in Indonesia.

Objective: To determine whether paternal smoking is associated with an increased risk of child malnutrition among families in rural Indonesia.

Methods: The relation between paternal smoking and child malnutrition was examined in a population-based sample of 438 336 households in the Indonesia Nutrition and Health Surveillance System, 2000-2003. Main outcome measures were child underweight (weight-for-age Z score <-2) and stunting (height-for-age Z score <-2) and severe underweight and severe stunting, defined by respective Z scores <-3, for children aged 0-59 months of age.

Background: Recent studies suggest an association between polyunsaturated fatty acids (PUFAs) and the development of chronic kidney disease. The aim of this study was to examine the relationship between PUFAs and renal function in older adults.

Methods: We performed a cross-sectional and prospective analysis of 931 adults, > or = 65 years old, enrolled in the InCHIANTI study, a population-based cohort in Tuscany, Italy.

Background: Oxidative stress has been implicated in sarcopenia and the loss of muscle strength with aging, but the relationship between oxidative stress and decrease in muscle strength and physical performance has not been well characterized. Serum protein carbonyls are markers of oxidative damage to proteins and are caused by oxidative stress.

Methods: Serum protein carbonyls were measured at baseline and compared with a decrease in walking speed and development of severe walking disability (inability to walk or walking speed <0.

Unlabelled: We prospectively examined vBMD and structural bone parameters assessed by QCT among participants of the InCHIANTI study over a 6-yr follow-up. Periosteal apposition occurred both in men and women. Endocortical resorption causes bone loss in older women despite periosteal apposition.

The pathogenesis of malarial anemia is incompletely understood. Hepcidin, a recently discovered peptide hormone, is a major regulator of iron metabolism and is thought to play a central role in the anemia of chronic inflammation. The specific aim of the study was to characterize the association between urinary hepcidin, hemoglobin, and parasitemia in 199 patients presenting for evaluation of Plasmodium falciparum malaria in Ghana.

Long-term diabetic patients exhibit major clinical gastrointestinal problems, such as diarrhea and constipation. In recent years, water channel protein, aquaporin 1 (AQP1) has been identified in the enteric nervous system (ENS). We have examined the pathological changes in AQP1 immunoreactive (IR) neurons in streptozotocin-induced (STZ) diabetic rats.

Subjects: A total of 2092 adults aged 65 and older, in the third National Nutrition Examination Survey, Phase 2 (1991-1994) (NHANES III).

Methods: Examination of the relationship between serum selenium and hematological indices in NHANES III.

Background: Although selenium plays an important role in muscle function, the relation between circulating selenium and muscle strength in elderly adults has not been characterized.

Aging is associated with a loss of muscle strength, and, in turn, loss of muscle strength has been associated with increased risk of frailty, disability and mortality. The factors that contribute to loss of muscle strength with aging have not been well characterized. Selenium is important in normal muscle function because of its role in selenoenzymes that protect muscle against oxidative damage.

Although it has been thought that child immunization programs may miss the children who are in greatest need, there are little published quantitative data to support this idea. We sought to characterize malnutrition and morbidity among children who are missed by the childhood immunization program in Indonesia. Vaccination and morbidity histories, anthropometry, and other data were collected for 286,500 children, aged 12-59 months, in rural Indonesia.
