- OBJECTIVE: In view of the increasing prevalence of obesity worldwide, understanding the role of the recently discovered adipokines leptin and adiponectin is of high clinical relevance. The aim of the present study was to assess the association between levels of leptin and adiponectin with age, known cardiovascular risk factors and to establish whether there are differences between men and women of the general population.METHODS: A total of 98 men and 107 women of the general population, aged between 20 and 74 years, underwent a medical examination at a clinical research center and fasting morning blood samples were also taken.RESULTS: Leptin (mean 7.5 μg l(-1) in men and 16.0 μg l(-1) in women) and adiponectin (mean 7.3 mg l(-1) in men and 11.9 mg l(-1) in women) levels were higher in women than men (Ps < 0.001). Both leptin and adiponectin levels increased with advancing age in both men and women (Ps < 0.05). Leptin was highly associated with factors for metabolic syndrome in men while in women, leptin was highly associated with inflammatory factors. Adiponectin was associated with blood lipids in both men and women, and glucose homeostasis more in women than in men.CONCLUSIONS: Leptin and adiponectin levels were ∼2 times and 1.5 times higher in women than in men, respectively. In addition, although leptin and adiponectin were associated to CVD risk factors in both men and women, we observed differences in specific CVD risk factor groups between men and women. These differences may be due to different regulatory mechanisms and effects of these adipokines in men and women.

- Objective. There are few prospective studies of the prevalence of colonic neoplasia in the normal population. In order to properly evaluate screening-protocols for colorectal cancer in risk groups (e.g., older subjects or those with a family history), it is essential to know the prevalence of adenomas and cancer in the normal population. Methods. A prospective population-based colonoscopy study on 745 individuals born in Sweden aged 19-70 years was conducted (mean age 51.1 years). All polyps seen were retrieved and examined. Results. Out of the 745 individuals 27% had polyps, regardless of kind. Adenomas were found in 10% of the individuals and finding of adenomas was positively correlated to higher age. Men had adenomas in 15% and women in 6% of the cases. Women had a right-sided dominance of adenomas. Hyperplastic polyps were seen in 21% of the individuals. The presence of hyperplastic polyps was significantly positively correlated to the presence of adenomas. Advanced adenomas were seen in 2.8% of the study participants, but no cancers were detected. Conclusion. One in 10 healthy subjects had an adenoma but advanced adenomas were uncommon. Men and women have a different adenoma prevalence and localization. The results provide baseline European data for evaluating colonoscopy screening-protocols for colorectal cancer risk groups, and the findings may have implications for colon cancer screening in the normal, otherwise-healthy population.

- We aimed to analyze associations between adiponectin, ghrelin and leptin with anthropometric and metabolic markers in men and women with Metformin-treated type 2 diabetes (n=53), recruited from a trial of relaxation therapies. Anthropometrical measures and fasting blood samples were assessed on three occasions: at baseline, and after 10 and 24 weeks: BMI, waist, HbA1c, insulin, glucose, adiponectin, leptin, fasting ghrelin, high sensitivity C-reactive protein (CRP), tumor necrosis factor α (TNF- α) and interleukin 6 (IL-6). HOMA2ir and HOMA2s were calculated from fasting glucose and insulin, and adiponectin/leptin and adiponectin/HOMA2ir ratios were calculated. In men, higher leptin and lower adiponectin/leptin ratio correlated with insulin and insulin resistance, and in women lower ghrelin with insulin and insulin resistance. In multivariate linear regression, higher levels of leptin were associated with insulin resistance among men, but not among women. Among women, insulin resistance was associated with lower adiponectin/leptin ratio and ghrelin. Factor analysis showed that leptin in women was closely related to anthropometric variables, but in men both related to anthropometric and inflammatory variables. Gender differences could indicate different pathophysiologic mechanisms of insulin resistance and type 2 diabetes among men and women, where leptin possibly could be a better marker among men, and ghrelin among women.
