The aim of this paper is to assess the impact of living in Saudi Arabia on expatriate employees and their families' behavioural cardiovascular risk factors (BCVRFs), and to examine the association between changes in BCVRFs and metabolic syndrome (MetS). A cross-sectional study was conducted on 1437 individuals, aged ≥ 18 years, from King Saud University in Riyadh, Saudi Arabia. We used the World Health Organization STEPS questionnaire to ask every participant questions about BCVRFs twice: (1) to reflect their period of living in Saudi Arabia and (2) to shed light upon life in their country of origin. Their mean age was 40.9 (11.7) years. The prevalence of BCVRFs was as follows: tobacco use in 156 (11%), physical inactivity in 1049 (73%) low intake of fruit and vegetables in 1264 (88%) and MetS in 378 (26%). Residing in Saudi Arabia had reduced physical activity and intake of fruit and vegetables. There was also a significant increase in the fast food consumption. In conclusion, living in Saudi Arabia had a significant negative effect on BCVRFs. However, there was no statistically significant association between changes in fruit and vegetable intake and physical activity and MetS status, except that intake of fast food was lower among participants with MetS.

“…Excess body weight and obesity, defined by the WHO as the abnormal or excessive accumulation of fat, is posing a growing threat to health in countries worldwide (20,21). Excessive weight is not only linked to an increased risk of developing chronic disease, but has also been demonstrated to increase the risk of developing reproductive disorders (8,22,23).…”

Male infertility is a complex, multifactorial and polygenic disease that contributes to ~50% cases of infertility. Previous studies have demonstrated that excess weight and obesity factors serve an important role in the development of male infertility. An increasing number of studies have reported that resveratrol may regulate the response of cells to specific stimuli that induce cell injury, as well as decrease germ cell apoptosis in mice or rats. In the present study, the semen quality and serum sex hormone levels were evaluated in 324 men, which included 73 underweight, 82 normal weight, 95 overweight and 74 obese men. All patients were referred to The Reproductive Medicine Center of Shanxi Women and Infants Hospital (Taiyuan, China) between January 2013 and January 2015. The aim of the present study was to investigate the effects of resveratrol treatment on the motility, plasma zinc concentration and acrosin activity of sperm from obese males. The sperm concentration, normal sperm morphology, semen volumes, DNA fragmentation rates and testosterone levels in men from the overweight and obese groups were markedly decreased when compared with men in the normal weight group. In addition, the progressive motility, seminal plasma zinc concentration and spermatozoa acrosin activity were notably decreased in the obese group compared with the normal weight group. However, estradiol levels were significantly increased in the overweight, obese and underweight groups compared with the normal weight group. Notably, semen samples from obese males with astenospermia treated with 0–100 µmol/l resveratrol for 30 min demonstrated varying degrees of improvement in sperm motility. When these semen samples were treated with 30 µmol/l resveratrol, sperm motility improved when compared to other doses of resveratrol. Therefore, 30 µmol/l resveratrol was selected for further experiments. Upon treatment of semen samples with resveratrol (30 µmol/l) for 30 min, the seminal plasma zinc concentration and spermatozoa acrosin activity increased significantly in the experimental group compared with the control group. These data suggest that male obesity negatively impacts on male reproductive potential, not only through altering hormone levels, but also by directly altering sperm function. In addition, resveratrol may have a therapeutic and protective effect against obesity-induced abnormalities in semen.

Association between length of residence and overweight among adult immigrants in Portugal: A nationwide cross-sectional study

BackgroundDespite the importance of immigrant population in Portugal few studies have analyzed the patterns of overweight/obesity in this subpopulation. The aims of this study are: (i) describe and compare the prevalence of overweight between immigrants and natives in Portugal; (ii) analyze the association between length of residence and overweight among adult immigrants in Portugal.MethodsA cross-sectional study (2005–2006) in a representative sample of the Portuguese population from national territory, including the Autonomous Regions of Azores and Madeira. The final sample comprised 31,685 adult participants (≥19 years old), of whom 4.6% were immigrants. Country of birth was used to determine immigrant condition. Logistic regressions were conducted to investigate the association between overweight (dependent variable) and length of residence (exposure), adjusting for all covariates in the study. A 5% confidence level and 95% CI were considered.ResultsThe percentage of immigrants that are overweight [44.9% (95% CI: 42.3; 47.5)] was lower than for natives [52.8% (95% CI: 52.2; 53.4)]. The migrant condition, after adjusted for sociodemographic variables, was not associated with overweight [OR 1.004 (95% CI: 0.998; 1.010)]. Among immigrants, being women [OR 0.585 (95% CI: 0.583; 0.587)], not married [OR 0.784 (95% CI: 0.781; 0.787)] and with a higher education [OR 0.481 (95% CI: 0.478; 0.483)], are probably protective factors of being overweight. Adjusting for other factors, the odds of being overweight for a long-term immigrant (≥15 years) was 1.3 times higher [OR 1.274 (95% CI: 1.250; 1.299)] than for the newcomers (<4 years).ConclusionsThe prevalence of overweight was higher for natives than immigrants. Length of residence (≥15 years) was positively associated with prevalence of overweight, among adult immigrant population. In the future, understanding dietary patterns and acculturation process may be important for health immigrant studies.
