Food items consumed by students attending schools in different socioeconomic areas in Cape Town, South Africa.
Nutrition. 2006 Mar; 22(3):252-258.We investigated the food consumption patterns of adolescent students at schools. Our findings are intended to reveal the overall nutritional quality of foods eaten by students at school, including foods brought to school and foods purchased at school. A questionnaire was completed by 476 students, mostly from grades 7 and 10, from 14 schools in Cape Town, South Africa. The schools were representative of the various ethnic groups and socioeconomic strata of the population. The questionnaire requested information on eating habits at school, foods brought to school and food purchases, and breakfast consumption before school. We also tested whether students knew which foods are healthy and which are less healthy choices. The students were mostly 12 to 16 y of age (mean age 14.5 y). The large majority had breakfast before school (77.8%) and ate at school (79.7%). Food was brought to school by 41% to 56%, whereas 69.3% purchased food at school, mainly at the school store (tuck shop). Predefined “unhealthy” foods brought to school outnumbered “healthy” ones by 2 to 1. Among students who purchased food at school, 70.0% purchased no healthy items, whereas 73.2% purchased two or more unhealthy items. With six foods 84% of students correctly stated whether they were healthy or unhealthy; however, with cola drinks, samoosas (deep-fried pastry with spicy filling), and pies, only 47% to 61% knew that these were less healthy choices. Students’ scores on this question were unrelated to whether they purchased healthy or unhealthy foods. Students who attended schools of high socioeconomic status were twice as likely to bring food to school (64.7% versus 31.0%, P < 0.001), scored higher marks on the quiz of healthy versus unhealthy foods (P < 0.01), but were no more likely to purchase healthy food. The large majority of food eaten by adolescent students in Cape Town is classified as being unhealthy choices. This applies to foods brought to school and food purchases. Consideration needs to be given to policy measures to improve this situation and to improve education of students and their parents. (author's)
Health Promotion International. 2004; 19(2):189-196.A survey of students’ smoking in China (n = 1896), comparing medical students with college students in nonmedical majors, was carried out to determine whether a medical education has a preventive effect on smoking uptake. The survey, sampling students from 12 universities in three cities, found no significant differences between medical and non-medical students in smoking prevalence (40.7% versus 45.1% for males, 4.4% versus 6.0% for females), in ‘ever smoked’ groups, in ‘ever smoked 100 cigarettes’ groups or in years of smoking. For both student groups, smoking prevalence increased with age and with years of college. However, one significant difference was found among the smokers: medical students were more likely to be occasional smokers than were non-medical students (75.3% occasional smokers among medical students who smoked versus 60.6% among non-medical students). These results suggest that a medical education had little effect on these students’ decisions to smoke, but that it may have modified their consumption level. Future studies are needed to ascertain factors affecting the decision to smoke and to identify possible early adopters of a nonsmoking culture in China. Action on a societal level is urgently needed to change Chinese social norms regarding smoking. (author's)
American Demographics. 1984 Apr; 6(4):16-21.Add to my documents.
In: Council of Europe. Proceedings of the European Population Conference 1982 (Strasbourg, 21-24 September 1982). Strasbourg, France, Council of Europe, 1983. 291-313.The possible drawbacks and adverse effects of the current population trend of the fall in fertility and steady aging of the population were analyzed. Areas in which links may exist between the economy and population trends, which, in a European context, appeared most pertinent were chosen. It is generally considered that a reduction in the number of births well result in a reduction in certain areas of public expenditure. Thus, the "numbers" effect would appear to be favorable as far as public finance is concerned. Reduction in education expenditure could offset the increase in health expenditure. The education sector is rapidly affected by a decline in the number of births, and the impact of demographic fluctutations is felt for many years as the cohorts grow older. Germany, where the birth rate has fallen markedly, provides valuable information about what can happen in such a case and illustrates the need to adapt education facilities. Focus is on the number of pupils, demand for teachers it is possible that education costs may be somewhat reduced, health costs and social security contributions will definitely increase. The relationship between health expenditures and age can be depicted by means of a U-shaped curve. The largest consumers of medical care and advice are children under the age of 1 year and adults over the age of 65. A sudden fall in the birth rate may reduce health expenditure, but since the aging of the population continues inexorably, what is saved on the youngest will be used to care for the oldest. The underlying tendency imposed by the changes in the structure of population until the end of the century will be to reinforce the upward trend in expenditure. Social security expenditure clearly will be much more strongly affected by demographic trends than other forms of expenditure. There is no demographic reason why overall household consumption should fall since, assuming that there are no economic fluctuations, per capita income is likely to increase. With a declining population growth, the building of housing to meet demographic needs will also diminish. Since such facilities as schools, hospitals, housing, and transport, are generally planned from a longterm standpoint, decisions to build may be delayed, possibly indefinitely, because of variations in population size. If present demographic conditions persist, all regions should, in the long run and to varying degrees, experience population decline. The demographic conditions in which Europe is going to live will not necessarily damage production capacity, but they will make it more difficult to develope and adapt that capacity.
