Methods: The incidence rates of testicular and prostatic cancers in 42 countries (region) were correlated with the dietary practices in these countries. These data came from the cancer rate database (1988–1992) and the food supply database (1961–1990) provided by the Department of Environmental Health, Medical University of Yamanashi, Japan. Results: The incidence rates of testicular and prostatic cancers varied greatly from country to country but in China the rates of the both malignancies were lower than that of USA and Japan. This may be due to the difference in lifestyle, especially in dietary practices. Among the food items we examined, cheese was most closely correlated with the incidence of testicular cancer at ages 20–39, followed by animal fats and milk. The correlation coefficient (r) was the highest (r=0.804) when calculated for cheese consumed during the period of 1961–1965 (maternal or prepubertal consumption). Stepwise-multiple-regression analysis revealed that cheese (1961–1965) made a significant contribution to the incidence of testicular cancer. Multiple coefficient (r) is 0.920. As far as prostatic cancer was concerned, milk was most closely correlated (r=0.711) with its incidence, followed by meat and coffee. Stepwise-multiple-regression analysis identified milk, meat, butter and coffee as significant factors contributing to the incidence of prostatic cancer (R=0.993). The results of our study suggest a role of milk and dairy practices in the development of testicular and prostatic cancers.展开更多

The Ghana Health Service in 2007 reported a national prevalence of diabetes of 11.6%, 27.8% for hypertension and 25% of women were reported to be overweight. Adolescents usually adopt lifestyles that negatively affect their nutritional and health status and increase their risk for development of diet-related chronic diseases later in life. The study was therefore carried out to investigate adolescents’ knowledge of diet-related chronic diseases and its influence on their dietary practices. The study design was a cross-sectional survey involving 313 adolescents aged 14 18 years from public and private senior high schools. Structured interviews and diet assessment methods were used to collect information on respondents’ knowledge of diet-related chronic diseases and dietary practices. The data collected were analyzed using the SPSS program version 16. The Chi-square test and ANOVA were used to determine the relationships between respondents’ knowledge of diet-related chronic diseases and dietary practices. The results revealed that knowledge of diabetes, hypertension and obesity were low among the respondents with most of them (89.2%) having fair to poor knowledge of the diseases. Eighty-eight percent of the adolescents ate three or more times in a day. Meals mostly skipped were breakfast and lunch. Dietary diversity of the respondents was generally poor. There was a significant relationship between knowledge of diet-related chronic diseases and the dietary practices of the adolescents. As knowledge of the diseases increased, dietary diversity also improved.展开更多

The objective of this study was to identify the local dietary practices of the schools teachers in Jeddah, western Saudi Arabia. A Cross-section observational study using a pre-designed questionnaire to identify the local pattern of dietary practices during school day of a representative sample of schools teachers was conducted in Jeddah. The questionnaire was piloted and administered to a sample of 140 teachers working in 15 schools across Jeddah. A total of 140 Saudi teachers participated. The mean age of the sample was 34.9 ± 6.1 years. Two thirds (66.4%) were females. Overall, 40.5% were overweight and 22.4% were obese. During the school day, tea and Arabic coffee were the commonest daily consumed drinks (67.9%, 65.7% respectively). Almost half of the sample consumed dates on a daily basis (51.4%). Breads and cheese sandwiches were always consumed by 45% and 33.6% respectively. Two thirds of females 67.7% and 55.3% of males were used to have breakfast and/or snack with their colleagues at school. Males preferred to purchase ready-made traditional foods from outside while females preferred the schools canteens. The percentages of overweight and obesity were higher among males compared to females (46.5 versus 37%) and (25.6% versus 20.5%) respecttively. It is concluded that the dietary practices of Saudi school teachers during school day vary according to gender. Findings indicate the need for dietary modification programs directed towards schools teachers in populations which report high prevalence rates of diabetes of similar cultural backgrounds.展开更多
