“…The gradual increase in the incidence of overweight and obesity over time indicates that the greater prevalence rates are not just a recent trend (Parikh et al, 2007). Similar results reporting a higher annual overweight incidence rate (2.6%) than obesity (1.1%) were found in an African population (Nemesure et al, 2008) rates among women almost twice that of men. Direct comparisons with other studies as regards annual incidences should be interpreted with caution and have been used here strictly for comparative purposes.…”

“…However, these data are of a cross-sectional nature or the result of trend studies which compare prevalence rates reported in surveys with independent samples over time. Prevalence data do not provide estimates on incidence nor on the causal relationship between obesity and its associated factors, thus making it difficult to target those at highest risk (Nemesure et al, 2008). More long-term follow-up is required to allow a rigorous evaluation of the temporal relations between exposure and disease risk (Mujahid et al, 2005;Williamson et al, 1991;Vasan et al, 2005).…”

a b s t r a c t a r t i c l e i n f oObjective. To study the changes in body mass index (BMI) in a population-based cohort and their relationship with sociodemographic variables in a Mediterranean-country.Method. A prospective population-based cohort with 8-year follow-up. The data used derive from the Cornellà-Health-Interview Survey Follow-up (CHIS.FU). 1008 people aged ≥ 20 years (females = 508; males = 500) were interviewed in 1994 and in 2002, providing self-reported weight and height data. The BMI was compared using the Wilcoxon test for paired data. Changes in the BMI were calculated and their relationship with sociodemographic-variables and lifestyles using multivariate Breslow-Cox regression.Results. 28.1% of participants had changed from normal-BMI in 1994 to overweight in 2002 (women = 25.6%; men = 31.6%). 16.8% increased from overweight to obesity (women = 25.8%; men = 11.2%). The cumulative incidence of overweight: women = 26.4%; men = 34.0%. The cumulative incidence of obesity: women = 29.9%; men = 13.1%. The cumulative age and sex-adjusted incidence of overweight showed a significant relationship with marital-status (married: RR = 2.0; 95% CI: 1.2-3.4, divorced/ widowed: RR = 4.0; 95% CI: 1.7-9.3) and moderate alcohol-consumption (RR = 1.86; 95% CI: 1.1-3.1). We observed a decreased age-adjusted risk in the incidence of obesity for men (RR = 0.49; 95% CI: 0.3-0.8).Conclusion. The observed changes in the increase in the incidence of obesity and overweight indicated a similar evolution in the obesity epidemic regardless of Mediterranean dietary patterns in our population.

“…Anthropometric measurements [including height, weight, body-mass index (BMI), waist circumference (WC), hip circumference (HC) and waist–hip ratio (WHR)] above the upper quintile were considered high, those below the lowest quintile were classified as low and all others were defined as intermediate. Although standard cutpoints for these variables have been defined, the distribution of body size in Barbados is somewhat different than in other populations 10,11. As such, quintiles were chosen to better quantify these measurements.…”

The Barbados National Cancer Study (BNCS) is a nationwide case‐control study investigating environmental and genetic factors for breast cancer (BC) in a predominantly African‐origin population with similar ancestry as African‐Americans. This report evaluates associations of incident BC in the BNCS to various factors, including demographic, anthropometric, reproductive and family history variables, not investigated previously in this population. The BNCS included 241 incident BC cases and 481 age‐matched female controls, with mean ages of 57 and 56 years, respectively. In addition to a reported family history of BC in a close relative [odds ratios (OR) = 3.74, 95% CI (1.41, 9.90) in a parent; OR = 3.26 (1.47, 7.21) in a sibling], other factors associated with BC were older age at first full‐term pregnancy [OR = 1.04 (1.00, 1.07)] and having a history of benign breast disease [OR = 1.88 (1.19, 2.99)]. Increased parity reduced the risk of BC [OR = 0.34 (0.15, 0.77) among those with ≥3 children]. The reproductive patterns of African‐Barbadian (AB) women tended to differ from those of African‐American (AA) women (later age of menarche, earlier age at first pregnancy, higher frequency of lactation and infrequent use of exogenous hormones) and could help to explain their considerably lower postmenopausal incidence of BC. The relationship between reported family history and BC, combined with the associations noted for several reproductive and other variables, supports the genetic and environmental contributions to BC, which may vary in populations across the African diaspora. Further investigations of other populations may clarify these issues. © 2008 Wiley‐Liss, Inc.

“…African-Barbadians have similar characteristic patterns of body size and fat distribution as African-Americans, with lower visceral and more subcutaneous fat than populations of European descent (3,4). While it has been postulated that obesity plays a role in the pathogenesis of prostate cancer, there is conflicting evidence on the relationship between prostate cancer and body size (5)(6)(7).…”

Background: The relationship between central adiposity and prostate cancer remains unclear. Methods: This report includes 963 newly diagnosed cases of histologically confirmed prostate cancer and 941 randomly selected age-matched controls ascertained from the population-based Prostate Cancer in a Black Population study conducted between July 2002 and January 2011 in Barbados, West Indies. Trained nurse interviewers obtained data on height, weight, waist and hip circumferences, family and medical history, and lifestyle factors. ORs and 95% confidence intervals (CI) were used to assess associations between anthropometric measures and prostate cancer.Results: A two-fold increased risk of prostate cancer was found among men in the highest quartile of waist-hip ratio compared with those in the lowest quartile (OR ¼ 2.11, 95% CI, 1.54-2.88). Similarly, men with the largest waist circumferences had an OR of 1.84 (95% CI, 1.19-2.85) compared with those with the smallest waist sizes.Conclusions: These results suggest that measures of central rather than global adiposity may be more predictive of prostate cancer, especially in westernized African populations, where patterns of visceral fat distribution are different than other groups.Impact: The findings highlight the need to further elucidate the mechanisms underlying the relationship between central adiposity and prostate cancer in populations of predominantly African descent.
