Objectives:Reliable evidence is the keystone for any noncommunicable disease (NCD) prevention plan to be initiated. In this study we carried out a risk factor investigation based on the WHO Stepwise approach to Surveillance (STEPS).Methods:The study was conducted on 1000 adults between 15 and 64 years of age living in Ardabil province, north-west Iran during 2006, based on the WHO STEPS approach to surveillance of risk factors for NCD. At this stage only the first and second steps were carried out. Data were collected through standard questionnaires and methods analyzed using STATA version 8 statistical software package.Results:29.0% of men and 2.6% of women were current daily tobacco smokers. The mean number of manufactured cigarettes smoked per day was 18.9 among current daily smokers. Smoking was most prevalent among men of low-income families and those of lower education. The mean body mass index (BMI) was 26.6 kg/m2, and was significantly correlated with systolic blood pressure. 58.9% were overweight or obese; 18.0% had raised blood pressure and 3.7% had isolated systolic hypertension. The mean number of servings of fruit consumed per day was 1.1; 33.1% had low levels of activity. Combined risk factor analysis showed that 4.1% of participants were in the low-risk group (up to 5.1% among men and 3.2% among women). Those in the high-risk group comprised 25.6% in the 25- to 44-year age group and 49.7% in the 45- to 64-year age group. Mean BMI increased by age in both sexes at least at the first three decades of adult life.Conclusion:Based on observed status of risk for cardiovascular health, burden of cardiovascular diseases is expected to increase if an effective prevention strategy is not undertaken.
Fertility is the main element affecting hatchability as an important indicator in breeder flocks’ performance. Roosters’ aging reduces their fertility. Using additives such as selenium helps to delay this reduction through antioxidant properties of Se. Replacing inorganic Se by the nano form in poultry diet improves fertility. The aim of this study was to assess effects of different amount of nano-Se on SelP, GPx4 and SelW gene expression in broiler breeder rooster’s testis. A total of 30 fifty-weeks-old broiler breeder males were randomly divided into five groups including a control group (fed basal diet) and four treatments containing basal diet plus 0.3 mg/kg sodium selenite (1), 0.15 mg/kg nano-Se (2) 0.3 mg/kg nano-Se (3) and 0.6 mg/kg nano-Se (4). The results indicated that mRNA expression levels of SelP, GPx4 and SelW genes increased significantly (p<0.05) after dietary supplementation of nano-Se compared to control and sodium selenite groups. In conclusion, dietary supplementation of nano-Se was more effective than sodium selenite on mRNA expression level of tested genes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
