Health-related lifestyles and risk behaviours among students living in Alexandria University Hostels.

We assessed health-related lifestyles and their determinants among 600 Alexandria University students living in university hostels. Data were collected by questionnaires, and anthropometric and blood pressure measurements were taken. Most students were not satisfied with their situation in terms of accommodation, health and support. About 86% ate unhealthy diets, 33.8% were physically inactive, 25.3% were overweight or at risk of becoming overweight, 17.5% of male students were current smokers and 32.2% had poor sleep behaviours. About 28% of the students adopted 3 or more risk behaviours. About 23% reported low perceived health status and 80.3% felt they had low to moderate social support. There were significant sex differences regarding some behaviours.

Measurement of KAP concerning hepatitis B among secondary school students in Alexandria.

Hepatitis B infection is a serious health problem throughout the world. Success in the prevention of this disease with its fatal consequences depends to a large extent on the adolescents' level of knowledge and their awareness about it. As well as their attitude and different risk behavior they might practice at this age. The aim of the present study was to assess the secondary school students' level of knowledge about hepatitis B and to record their perceptions, attitudes and practices towards it. Also to identify their health locus of control towards the disease. The studied sample included 643 students of both sexes representing different senior levels in one educational sector in Alexandria. The used technique was self-administered questionnaire. Results revealed that (55.2%) of the studied sample had fair level of knowledge about hepatitis B Girls had more negative attitude towards the disease than boys. About one half of the students (50.4%) were not vaccinated against the disease. Also, the majority of students had internal health locus of control regarding hepatitis B. It is recommended to integrate knowledge about hepatitis B within formal and informal school programs. Community campaigns for vaccinating the adolescents against the disease should be carried out.

Improving students' knowledge, attitude and practice towards cancer prevention through a health education program. Part II.

A health education program for cancer risk reduction was conducted among 649 students out of 896 for whom Knowledge, Attitude and Practice (KAP) had been obtained at the initial study. Three hundred and sixteen students acted as the intervented group and three hundred and thirty three were the control group. There was a great improvement in the percentage of correct knowledge answers in the majority of the questions from pre to post tests especially for the questions about the effect of excessive use of fatty foods (76.3%) and excessive use of salty foods (68.0%) on the occurrence of cancer. After the program, at least 87% or more of the students recognized the hazards of risky food, 86.1% knew that mothers who do not breast feed their infants have a greater chance of getting cancer breast, 51.3% responded correctly to the question about the effect of oral contraceptive pills after 40 years. More than 86% recognized the serious effect of prolonged exposure to the sun. A significant shift toward positive attitude was found especially with the item "I am very afraid to know that I have cancer, so I avoid going to the physician" (76.9%). It was found that 94% of the students agreed that there is a relation between the type of food and cancer. The students showed significant increases in median practice scores from pre to post tests and the larger gain associated with participants in the program (9.97%). The majority of the students reported increases in their daily consumption of fruits, cereals, leafy vegetables and salad. These significant changes in KAP scores from pre to post tests were noticed for both sexes, different social classes and different educational grades.

Assessment of students' knowledge, attitude and practice concerning cancer and its prevention. Part I.

Cancer is a serious public health issue, but it is increasingly regarded as preventable. The present study was conducted to assess students' knowledge, attitude and practice about cancer. A questionnaire was developed by the researchers and completed by 896 secondary school students from the middle zone of Alexandria Governorate. Females had a significantly higher awareness than males as regards the relationship between not eating vegetables and fruits, environmental effects, exposure to irradiation or to the sun for long periods and the hazards of getting cancer. Third grade students were significantly more knowledgeable than the other two grades (H=11.43, p<0.01). Only 4.5% of the participants had satisfactory levels of knowledge. Students in general expressed strong fear of cancer. Females were more worried than males either about themselves getting cancer or about others having it. More than 50% of the females liked to be friendly with children having cancer as compared to 37% of males. Only 12.3% of the students had a positive attitude towards cancer prevention. Males tended to consume healthier foods than females. Furthermore, 57% of the students demonstrated good practice. School education on cancer is extremely needed for these adolescents in order to correct misconceptions, provide accurate information and to develop a positive attitude towards cancer.

Self-efficacy for dietary behaviour concerning heart disease among Alexandria school pupils

A study of 1134 preparatory-school pupils was conducted to measure children's self-efficacy for selecting healthy food for the heart, to examine the relationship between self-efficacy and self-reported usual food consumption and to estimate test-retest reliability. Results revealed an acceptable estimate of internal consistency of dietary self-efficacy [Cronbach alpha = 0.76]. Over half the students exhibited a moderate level of self-efficacy and 42% a high level. Test-retest reliability of the scale was good [r = 0.65, Cronbach alpha = 0.79]. Usual food choice was the first best predictor of dietary self-efficacy [r = 0.44], followed by sex [boys had higher self-efficacy than girls] and then knowledge [r = 0.37].The three factors contributed to explain 25% of the variance
