Sex Differences in the Association of Socioeconomic Status With Obesity

OBJECTIVES This study investigated socioeconomic predictors of obesity in men and women. METHODS Data from the 1996 Health Survey for England were used to compare odds ratios for obesity by education, occupation, and 2 economic markers after control for age, marital status, and ethnicity. RESULTS Obesity risk was greater among men and women with fewer years of education and poorer economic circumstances and among women, but not men, of lower occupational status. CONCLUSIONS Higher educational attainment and higher socioeconomic status were associated with a lower risk of obesity in both men and women, whereas higher occupational status was associated with a lower risk only for women. The implications of these findings for understanding causes and prevention of obesity are discussed.

Demographic variation in nutrition knowledge in England

This paper describes a nutrition knowledge survey carried out on a cross-section of the adult population of England (n = 1040), looking at knowledge relating to current dietary recommendations, sources of nutrients, healthy food choices and diet–disease links. Serious gaps in knowledge about even the basic recommendations were discovered, and there was much confusion over the relationship between diet and disease. Significant differences in knowledge between socio-demographic groups were found, with men having poorer knowledge than women, and knowledge declining with lower educational level and socio-economic status. Possible reasons for these differences and implications for public education campaigns and socio-economic inequalities in health are discussed.

Public awareness of cancer in Britain: a population-based survey of adults

Objective:To assess public awareness of cancer warning signs, anticipated delay and perceived barriers to seeking medical advice in the British population.Methods:We carried out a population-based survey using face-to-face, computer-assisted interviews to administer the cancer awareness measure (CAM), a newly developed, validated measure of cancer awareness. The sample included 2216 adults (970 males and 1246 females) recruited as part of the Office for National Statistics Opinions Survey using stratified probability sampling.Results:Awareness of cancer warning signs was low when open-ended (recall) questions were used and higher with closed (recognition) questions; but on either measure, awareness was lower in those who were male, younger, and from lower socio-economic status (SES) groups or ethnic minorities. The most commonly endorsed barriers to help seeking were difficulty making an appointment, worry about wasting the doctors time and worry about what would be found. Emotional barriers were more prominent in lower SES groups and practical barriers (e.g. too busy) more prominent in higher SES groups. Anticipated delay was lower in ethnic minority and lower SES groups. In multivariate analysis, higher symptom awareness was associated with lower anticipated delay, and more barriers with greater anticipated delay.Conclusions:A combination of public education about symptoms and empowerment to seek medical advice, as well as support at primary care level, could enhance early presentation and improve cancer outcomes.

Knowledge, attitudes, and behavioral intentions in relation to the early detection of colorectal cancer in the United Kingdom.

BACKGROUND Colorectal cancer (CRC) mortality is high. Understanding the social, psychological, and cognitive predictors of early detection practices such as screening may help improve CRC outcomes. This study examined knowledge of CRC and the relationship between knowledge, attitudes to cancer, and intentions to engage in early detection behaviors for CRC in a national representative population sample. METHOD An interview-based survey was carried out in a British population sample of adults ages 16 to 74 years (n = 1637), assessing knowledge, attitudes, and intention with regard to colorectal cancer. RESULTS Knowledge levels were very low; 58% (n = 995) of respondents could not list any colorectal cancer risk factors and 24% (n = 393) were unable to identify any warning signs for cancer. Knowledge was lower among men (chi(2)[2] = 52.8, P < 0.0001), younger respondents (chi(2)[10] = 79.9, P <.0001), and those with less education (chi(2)[4] = 73.9, P < 0.0001). Attitudes to cancer were more negative among women (chi(2) [2] = 7.4, P = 0.025), younger participants (chi(2)[10] = 22.4, P = 0.013), and those with less education (chi(2) [4] = 75.0, P < 0.0001). Low knowledge was associated with negative attitudes (P < 0.0001) and both factors were associated with lower intentions to participate in colorectal cancer screening (P < 0.0001). Multivariate analysis indicated that attitudes partially mediated the effect of knowledge on screening intentions. CONCLUSIONS Increasing knowledge may reduce negative public perceptions of cancer which may impact positively on intentions to participate in screening.

Social and psychological impact of HPV testing in cervical screening: a qualitative study

Objective: Human papillomavirus (HPV) testing has been proposed for inclusion in the UK cervical screening programme. While testing may bring some benefits to the screening programme, testing positive for HPV, a sexually transmitted virus, may have adverse social and psychological consequences for women. The aim of this study was to examine the social and psychological impact of HPV testing in the context of cervical cancer screening. Method: In-depth interviews generating qualitative data were carried out with 74 women participating in HPV testing in England between June 2001 and December 2003. Purposive sampling was used to ensure heterogeneity in age, ethnic group, marital status, socioeconomic background, cytology, and HPV results among participants. Results: Testing positive for HPV was associated with adverse social and psychological consequences, relating primarily to the sexually transmitted nature of the virus and its link to cervical cancer. Women described feeling stigmatised, anxious and stressed, concerned about their sexual relationships, and were worried about disclosing their result to others. Anxiety about the infection was widespread, but the impact of testing positive varied. The psychological burden of the infection related to women’s relationship status and history, their social and cultural norms and practices around sex and relationships, and their understanding of key features of HPV. Conclusion: HPV testing should be accompanied by extensive health education to inform women and to de-stigmatise infection with the virus to ensure that any adverse impact of the infection on women’s wellbeing is minimised.

Testing positive for Human Papillomavirus in routine cervical screening: examination of psychosocial impact

Objective  To examine the psychosocial impact of testing positive for high risk human papillomavirus (HPV) among women attending primary cervical screening.

Barriers to cervical cancer screening attendance in England: a population-based survey

Objectives To explore barriers to cervical screening attendance in a population-based sample, and to compare barriers endorsed by women who were up-to-date with screening versus those who were overdue. We also tested the hypothesis that women who were overdue for screening would be more generally disillusioned with public services, as indexed by reported voting behaviour in elections. Setting A population-based survey of women in England. Methods Face-to-face interviews were carried out with 580 women aged 26–64 years, and recruited using stratified random probability sampling as part of an omnibus survey. Questions assessed self-reported cervical screening attendance, barriers to screening, voting behaviour and demographic characteristics. Results Eighty-five per cent of women were up-to-date with screening and 15% were overdue, including 2.6% who had never had a smear test. The most commonly endorsed barriers were embarrassment (29%), intending to go but not getting round to it (21%), fear of pain (14%) and worry about what the test might find (12%). Only four barriers showed significant independent associations with screening status: difficulty making an appointment, not getting round to going, not being sexually active and not trusting the test. We found support for our hypothesis that women who do not attend for screening are less likely to vote in elections, even when controlling for barrier endorsement and demographic factors. Conclusions Practical barriers were more predictive of screening uptake than emotional factors such as embarrassment. This has clear implications for service provision and future interventions to increase uptake. The association between voting behaviour and screening uptake lends support to the hypothesis that falling screening coverage may be indicative of a broader phenomenon of disillusionment, and further research in this area is warranted.

Attitudes towards HPV testing: a qualitative study of beliefs among Indian, Pakistani, African-Caribbean and white British women in the UK.

This study examined attitudes to human papillomavirus (HPV) testing among a purposively selected sample of women from four ethnic groups: white British, African Caribbean, Pakistani and Indian. The design was qualitative, using focus group discussion to elicit womens attitudes towards HPV testing in the context of cervical cancer prevention. The findings indicate that although some women welcomed the possible introduction of HPV testing, they were not fully aware of the sexually transmitted nature of cervical cancer and expressed anxiety, confusion and stigma about HPV as a sexually transmitted infection. The term ‘wart virus’, often used by medical professionals to describe high-risk HPV to women, appeared to exacerbate stigma and confusion. Testing positive for HPV raised concerns about womens sexual relationships in terms of trust, fidelity, blame and protection, particularly for women in long-term monogamous relationships. Participation in HPV testing also had the potential to communicate messages of distrust, infidelity and promiscuity to womens partners, family and community. Concern about the current lack of available information about HPV was clearly expressed and public education about HPV was seen as necessary for the whole community, not only women. The management of HPV within cervical screening raises important questions about informed participation. Our findings suggest that HPV testing has the potential to cause psychosocial harm to women and their partners and families.

The association between knowledge of HPV and feelings of stigma, shame and anxiety

Objectives: To test the hypotheses that (1) women who know that human papillomavirus (HPV) is sexually transmitted will expect to experience higher levels of stigma, shame and anxiety if they test positive for the virus than women who are not aware of the mode of transmission and (2) women who are aware of the high prevalence of HPV infection will expect to experience lower levels of stigma, shame and anxiety than women who underestimate its prevalence. Methods: A web-based survey in which information about HPV was manipulated to generate a 2×2 design (awareness that HPV is sexually transmitted v no awareness; awareness of the high prevalence of HPV v no awareness). Participants (n = 811) were female students. They were asked to imagine that they had tested positive for HPV. Outcome measures were expected stigma, shame and anxiety. Results: Great differences were observed in emotional reactions to imagining testing HPV positive between the four groups based on knowledge of HPV. Knowledge of the prevalence was associated with lower levels of stigma, shame and anxiety. Knowledge that HPV is sexually transmitted was associated with higher levels of stigma and shame, but not anxiety. Women who knew that HPV is sexually transmitted but not that it is highly prevalent had the highest scores for stigma and shame. Conclusions: Raising public awareness of the sexually transmitted nature of HPV has the potential to increase women’s feelings of stigma and shame if they test positive for the virus. However, our findings suggest that ensuring women’s awareness of HPV being common may reduce these feelings and also reduce anxiety, perhaps by “normalising” the infection.

Public awareness that HPV is a risk factor for cervical cancer

We assessed awareness of human papillomavirus (HPV) in a population sample of British women (n=1620) using similar questions to those in a survey in 2002. Only 2.5% cited HPV as the cause of cervical cancer without prompting; up from 0.9% in 2002. Public education about HPV is urgently needed.
