Testing at home--the screening of the future?

Cardiovascular diseases (CVD) and diabetes mellitus (DM) aremajor public health concerns in modern society. Although mortalityfrom CVD has decreased substantially in many European countriesin the past 30 years due to better prevention (e.g. encouragingpeople to stop smoking and discouraging people from starting)and better medicinal treatment, CVD remains the category ofdiseases with the highest number of life-years lost. Due tosedentary lifestyles and unfavourable nutrition habits, obesityhas developed into a new ‘epidemic’ with adverseconsequences for CVD and DM. Type 2 diabetes is     

Are the obese at greater risk for depression?

Two waves of data from a community-based study (Alameda County Study, 1994-1995) were used to investigate the association between obesity and depression. Depression was measured with 12 items covering Diagnostic and Statistical Manual of Mental Disorders: DSM-IV diagnostic criteria for major depressive episode. Following US Public Health Service criteria, obese subjects were defined as those with body mass index scores at the 85th percentile or higher. Covariates were age, sex, education, marital status, social isolation and social support, chronic medical conditions, functional impairment, life events, and financial strain. Results were mixed. In cross-sectional analyses, greater odds for depression in 1994 were observed for the obese, with and without adjustment for covariates. When obesity and depression were examined prospectively, controlling for other variables, obesity in 1994 predicted depression in 1995 (odds ratio (OR) = 1.73, 95% confidence interval (CI): 1.04, 2.87). When the data were analyzed with obesity defined as a body mass index of > or = 30, cross-sectional results were the same. However, the prospective multivariate analyses were not significant (OR = 1.43, 95% CI: 0.85, 2.43). Although these data do not resolve the role of obesity as a risk factor for depression, overall the results suggest an association between obesity and depression. The authors found no support for the "jolly fat" hypothesis (obesity reduces risk of depression). However, there has been sufficient disparity of results thus far to justify continued research.     

Vitamin D and Allergic Disease: Sunlight at the End of the Tunnel?

A role for vitamin D in the regulation of immune function was first proposed after the identification of Vitamin D Receptors in lymphocytes. It has since been recognized that the active form of vitamin D, 1α,25(OH)2D3, has direct affects on naïve and activated helper T cells, regulatory T cells, activated B cells and dendritic cells. There is a growing body of literature linking vitamin D (serum 25(OH)D, oral intake and surrogate indicators such as latitude) to various immune-related conditions, including allergy, although the nature of this relationship is still unclear. This review explores the findings of epidemiological, clinical and laboratory research, and the potential role of vitamin D in promoting the inappropriate immune responses which underpin the rise in a broad range of immune diseases.     

Did the strategy of skilled attendance at birth reach the poor in Indonesia?

OBJECTIVE: To assess whether the strategy of "a midwife in every village" in Indonesia achieved its aim of increasing professional delivery care for the poorest women. METHODS: Using pooled Demographic and Health Surveys (DHS) data from 1986-2002, we examined trends in the percentage of births attended by a health professional and deliveries via caesarean section. We tested for effects of the economic crisis of 1997, which had a negative impact on Indonesias health system. We used logistic regression, allowing for time-trend interactions with wealth quintile and urban/rural residence. FINDINGS: There was no change in rates of professional attendance or caesarean section before the programmes full implementation (1986-1991). After 1991, the greatest increases in professional attendance occurred among the poorest two quintiles -- 11% per year compared with 6% per year for women in the middle quintile (P = 0.02). These patterns persisted after the economic crisis had ended. In contrast, most of the increase in rates of caesarean section occurred among women in the wealthiest quintile. Rates of caesarean deliveries remained at less than 1% for the poorest two-fifths of the population, but rose to 10% for the wealthiest fifth. CONCLUSION: The Indonesian village midwife programme dramatically reduced socioeconomic inequalities in professional attendance at birth, but the gap in access to potentially life-saving emergency obstetric care widened. This underscores the importance of understanding the barriers to accessing emergency obstetric care and of the ways to overcome them, especially among the poor.
