Population-based mammographic screening in Singapore: what are participants' views?

Mammographic screening for breast cancer has been shown to be an effective tool for reducing mortality from the disease in many studies in the West, if high technical quality and acceptance by the target population are achieved. The objective of the Singapore Breast Screening Project was to determine if the same results could be obtained among local women by inviting a random sample of 69,500 women aged 50 to 64 years for a screening mammogram over two years. To date, the compliance rate among the women invited has been 41.7%. The objective of the present substudy was to determine participants' views on the accessibility and acceptability of organised mammographic screening. Of the three hundred women interviewed, 85% were satisfied with the information given prior to the visit, while 67% needed to change the original appointment given. The majority were satisfied with aspects of the visit such as waiting time, privacy and explanation given during the test. However, 35.1% reported at least moderate discomfort during mammography. A substantial proportion (39.7%) of attenders felt that there was very little hope of cure even if cancer was detected early. When asked the most important reason for attending, most indicated they had taken the opportunity for a free check-up to be assured they were well. Almost all (95.7%) reported a willingness to be screened again, but most would not be willing to pay for a mammogram at the current rates.

Factors determining acceptability of mammography in an Asian population: a study among women in Singapore.

Population-based mammographic screening has been shown to be effective in reducing breast cancer mortality in the West. In Singapore, a project carried out to determine the effectiveness of implementing such a program locally invited 28,000 women between the ages of 50 and 64 years for mammography. The current study, which was part of this larger project, was intended to determine factors contributing to the acceptance of mammographic screening among women in Singapore. A questionnaire was administered in-person to 300 attenders and 260 non-attenders. The respondents were compared with respect to basic demographic characteristics, previous preventive behavior, informal social support, and attitudes towards early detection. We found that screening attenders were more likely to be Chinese than Malays (14 percent of the population) or Indians (seven percent), and to be working outside the home (adjusted odds ratio [OR]) = 4.5, 95 percent confidence interval [CI] = 2.6-7.9). A greater proportion of attenders had a history of other screening tests such as the Pap smear (OR = 4.7, CI = 2.6-8.7 for recent smear compared with never having had a smear). They were also more likely to indicate a sense of personal susceptibility to cancer, but did not differ from non-attenders in terms of believing in cancer prevention, or of preferring to be told if they did have cancer. The strongest independent predictor of attendance, however, was encouragement by her spouse or family member. For women in this population to be persuaded effectively to participate in mammographic screening, it would be important to convince family members of the benefits of the test. At the same time, education targeted specifically at women of the appropriate age group should address the issue of the personal relevance of screening for breast cancer.

Cigarette smoking among school children in Singapore. Part III--Knowledge and attitudes towards smoking.

In the third article in this series which mainly assesses the knowledge of school children on the harmful effects of smoking, findings showed that the majority (90%) of school children surveyed were aware of the harmful effects. Current smokers appeared to be the least knowledgeable (69.4%) whilst non-smokers (89.3%) and experimenters (93.7%) were the most knowledgeable. Lung cancer (49%), smoking is bad for health (25%), smoking is bad for passive smokers (7%) and for heart disease (6%) were the most common responses given by the children on the specific ill effects caused by smoking. Smokers and non-smokers alike agreed that smoking is addictive, the proportions agreeing, once again, being lowest among smokers and highest among non-smokers. This trend was also observed when respondents were asked for their attitudes towards smoking--whether cigarette smoking was harmful and whether smoking made a person popular. The majority of respondents felt that a boy or girl who smoked "looked bad"--39% thought so of boys, while a higher proportion (55%), had the same impression of girls. The main reasons for giving up smoking given by ex-smokers were its harmful effects on health (49%), there being no more "kick" to it (16%), peer pressure (13%) and the disapproval of parents and teachers (13%). Among current smokers, at least half stated that they would like to stop smoking. Most of them had tried to kick the habit before but failed in their attempts. Finally, among the non-smokers, only 0.4% of boys and 0.1% of girls indicated that they might smoke in the future.

Cigarette smoking among school children in Singapore. Part II--Development of the smoking habit.

The second in this series on smoking among school children in Singapore aims to define the characteristics of young smokers. Results show that of respondents who had ever smoked, the median age of experimentation with smoking was 12 years. This was seen among boys as well as girls. The median age at which current smokers went on to smoke regularly was 14 years, approximately two years after trying their first cigarette. Friends and parents were the main sources of the first cigarette for all categories of smokers, whether they be ex smokers, experimenters or current smokers. Among the reasons as to why current smokers smoked, the leading two were "to relax" (46.4%) and "out of sheer curiosity" (22.3%). Boys tend more to smoke with friends of the same sex (40.6%) whilst girls preferred mixed company (45.5%) when they smoked. Fathers played a major role in the development and continuation of smoking among those who had ever smoked before--52.0% of boys and 51.6% of girls currently smoking reported that their fathers smoked as well.

Public awareness of AIDS in Singapore.

Singapore had 52 cases of AIDS as at June 1990. This places Singapore in the low-infection-load group of countries. Constant vigilance is necessary however. The Health education programme against AIDS in Singapore was launched in 1985. This first ever National Survey on public awareness of AIDS was carried out by the Research and Evaluation Department, Ministry of Health HQ, in late 1987, to assess the impact of the programme. It showed the level of knowledge of among Singaporeans to be high and comparable in many areas to that in the USA. The survey however also showed lack of credibility in the knowledge of AIDS among the public in certain important areas. This poses challenges to the public education programme.

Cigarette smoking among school children in Singapore. Part I--Smoking prevalence.

A cross sectional nationally representative survey of 33,110 school-going children in Singapore aged between 9 and 20 years was carried out to obtain, for the first time, baseline information on smoking among the school-going population in Singapore. The survey was carried out among students attending vocational institutes and public sector schools in Singapore in 1987. The overall smoking prevalence was found to be 2% (3% among boys and 0.2% among girls). Ex-smokers comprised 2% of respondents whilst those who had only experimented with smoking made up 9% of the respondents. Analyses of the data showed that cigarette smoking was more prevalent among Malays, among boys, among older children, and among the less academically inclined. On average, boys smoked a median of 20 cigarettes a week and girls, 12 cigarettes a week. On an international basis, the smoking prevalence among the school-going population in Singapore is significantly lower than that of developed countries like Australia, England and Wales and neighbouring countries such as Malaysia.
