vitamin d deficiency/obesity

OBJECTIVE Recent studies show a high prevalence of vitamin D deficiency in the general population, especially in the elderly. There are also studies reporting the same observations in the morbidly obese, although few of these studies have compared morbidly obese individuals with non-obese persons.

The study was conducted to understand better the mechanisms involved in liver changes when there is a combination of diet-induced obesity (DIO) and vitamin D deficiency (VDD). After 8 wk of feeding a control diet (C group) or a high-fat diet (HF), both with vitamin D, and counterpart groups without

Vitamin D deficiency (VDD) is associated with obesity and metabolic syndrome (MS). After bariatric surgery (BS), high rates of VDD often persist and some patients are refractory to the resolution of comorbidities. The aim of the present study is to analyse the relationship between the levels of

Background. It is unknown whether the coexistence of type 1 diabetes (T1D) and celiac disease (CD) increases the risk for vitamin D deficiency. Aims. To determine the vitamin D status and the risk for vitamin D deficiency in prepubertal children with both T1D and CD compared to controls, TID, and

Obesity and vitamin D deficiency represent major health problems among Saudi children, and have been linked to chronic diseases. Obese children are at risk of developing vitamin D deficiency, which appears to have negative influences on energy homeostasis, impeded bone mineralisation, insulin

Obesity is associated with lower vitamin D levels compared with normal weight subjects, and if levels are not replaced prior to bariatric surgery, this can increase fracture risk as bone density typically falls post-operatively. We analysed the effect of body mass index (BMI) on vitamin D levels in

Numerous studies highlighted the link between vitamin D deficiency and cardiovascular, autoimmune, metabolic diseases, and obesity. However, a clear role of vitamin D in these disorders is still unknown. Vitamin D deficiency in children can be a potential risk factor for developing diseases at a

METHODS To investigate the impact of vitamin D deficiency on insulin resistance and abnormal glucose homeostasis in obesity. RESULTS Sixty male C57BL/6 mice (3 months old) were fed a control diet (C-10% energy as fat) or a high-fat diet (HF-50% energy as fat), with or without vitamin D, for 8 weeks.

BACKGROUND Vitamin D status can influence insulin resistance. OBJECTIVE The aim of the study was to determine the prevalence of vitamin D deficiency in obese African-American (AA) adolescent females in a southeastern latitude and to determine the relationship of 25-hydroxyvitamin D [25(OH)D] with

OBJECTIVE To assess vitamin D dietary sources, intake and 25-hydroxyvitamin D status and their association with individual and sociodemographic characteristics in Mexican children. METHODS Data obtained from 2695 children aged 1-11 years from the Mexican National Health and Nutrition Survey (2012)

OBJECTIVE To determine whether the obese population is more likely to be vitamin D deficient compared to healthy and overweight individuals. METHODS A retrospective chart review was performed for patients seen in two ambulatory clinics in South Florida over a 1-year period (n=402). Patients' vitamin

Obesity affects the vitamin D status in humans. Vitamin D and long-chain n-3 polyunsaturated fatty acids (PUFA) provide benefit for the prevention of fractures and cardiovascular events, respectively, and both are involved in controlling inflammatory and immune responses. However, published

Childhood and adolescent obesity is an international public health problem leading to an increased risk of adulthood obesity, mortality and morbidity. Its prevalence is increasing in low-income populations, and we hypothesized it may be associated with vitamin D deficiency. Low vitamin D status is a
