Random Digit Dialling

Background This study describes the prevalence of (solo) masturbation, paying for sex and a range of other sexual practices among Australians. Methods: A representative sample of 20 094 men and women aged 16–69 years (participation rate among eligible people, 66.2%) were recruited by landline and mobile phone random-digit dialling and computer-assisted telephone interviews in 2012–13. Results: Many respondents (men, 72%; women, 42%) had masturbated in the past year. Half (51%) of the men and 24% of women had masturbated in the past 4 weeks. In the past year, more than two-fifths of respondents (men, 63%; women, 20%) had looked at pornography in any medium. Approximately 15% of men and 21% of women had used a sex toy. Digital-anal stimulation with a partner was practised by 19% of men and 15% of women, and oral-anal stimulation by 7% of men and 4% of women. Sexual role playing or dressing up were engaged in by 7–8%. Online sex, swinging, group sex, BDSM (bondage and discipline, ‘sadomasochism’ or dominance and submission) and fisting (rectal or vaginal) were each engaged in by less than 3% of the sample. Seventeen per cent of men said they had ever paid for sex; 2% had done so in the past year. Conclusion: Most of the solo practices studied were engaged in by more men than women, but women were more likely to have used a sex toy. Autoerotic activities are both substitutes for partnered sex and additional sources of pleasure for people with sexual partners.

Abstract Respondent-driven sampling (RDS) is an approach commonly used to recruit nonprobability samples of rare and hard-to-find populations. The purpose of this study was to explore the utility of phone- and web-based RDS methodology to sample sexual minority women (SMW) for participation in a telephone survey. Key features included (i) utilizing a national probability survey sample to select seeds; (ii) web-based recruitment with emailed coupons; and (iii) virtual processes for orienting, screening, and scheduling potential participants for computer-assisted telephone interviews. Rather than resulting in a large diverse sample of SMW, only a small group of randomly selected women completed the survey and agreed to recruit their peers, and very few women recruited even one participant. Only seeds from the most recent of two waves of the probability study generated new SMW recruits. Three RDS attempts to recruit SMW over several years and findings from brief qualitative interviews revealed four key challenges to successful phone- and web-based RDS with this population. First, population-based sampling precludes sampling based on participant characteristics that are often used in RDS. Second, methods that distance prospective participants from the research team may impede development of relationships, investment in the study, and motivation to participate. Third, recruitment for telephone surveys may be impeded by multiple burdens on seeds and recruits (e.g., survey length, understanding the study and RDS process). Finally, many seeds from a population-based sample may be needed, which is not generally feasible when working with a limited pool of potential seeds. This method may yield short recruitment chains, which would not meet key RDS assumptions for approximation of a probability sample. In conclusion, potential challenges to using RDS in studies with SMW, particularly those using virtual approaches, should be considered.

Aim The purpose of the study was to estimate the one-year prevalence of migraine among a population-based sample of Spanish adults. Method Men and women aged 18-65 years were selected at random according to quotas for age, sex, size of habitat (10,000 inhabitants, 10,001–50,000 inhabitants, 50,001 −200,000 inhabitants and 200,000 inhabitants) and residence proportional to the population size of the geographical location. A random-digit-dial, computer-assisted telephone interview (CATI) survey was conducted between April and July 2006. The 2004 International Headache Society operational diagnostic criteria were applied. Results From a total of 70,692 telephone calls and 26,255 (31.7%) valid contacts, 5,668 (21.6%) respondents completed the CATI survey. A total of 476 subjects (8.4%, 95% confidence interval [CI] 7.7-9.1%) with strict migraine and 236 with probable migraine (4.2%, 95% CI 3.7-4.7%) were recorded. The 1-year prevalence of total migraine (N = 712) was 12.6% (95% CI 11.6-13.6) (17.2% in females, 8.0% in males). The prevalence rates showed significant geographic variations, from 7.6% in Navarra to 18% in the Canary Islands. One-half of the subjects had migraine with aura. One-third of subjects were never diagnosed for migraine. Conclusions The one-year prevalence of migraine in Spain is 12.6%, with a prevalence of migraine with and without aura of 8.4% and probable migraine of 4.2%. These findings add data to the current understanding of migraine.

The Impact

ABSTRACTRelatively little is known about the factors in Canada which lead to osteoporosis and its concomitant fractures. The Canadian Multicentre Osteoporosis Study (CaMos) is a prospective cohort study which will estimate the incidence and prevalence of declining bone mass and fractures. The impact of osteoporosis in Canada will be assessed, including regional variation and the effect of various risk factors. The study will provide information for developing prevention programs. The cohort has been drawn from a random population-based sample of non-institutionalized men and women 25 years old or more and living within 50 km. of nine cities in Canada. Through telephone interviews 9,423 participants have been recruited. All answered an extensive questionnaire, and had physical measurements related to bone quality taken. This paper details the CaMos baseline and five-year follow-up protocol.

Several studies have explored a possible association between migraine and hyper- tension, with contradictory results. Because of this uncertainty the relation between blood pressure (BP) and migraine was studied in 10 366 men and 11 171 women in a population-based longitudinal study. A modified version of the 1988 International Headache Society criteria was used for diagnosis of migraine. Logistic regression analysis was used. The crude 1-year prevalence of migraine was 5.2% among men and 14.1% among women. No significant association was found between hypertension and migraine. For a one standard deviation (SD) increase in diastolic BP the probability of having migraine increased 14% ( P = 0.11) for men and 30% ( P < 0.0001) for women. For a 1-SD increase in systolic BP the probability of having migraine decreased 19% ( P = 0.007) for men and 25% ( P < 0.0001) for women. It was also found that for a 1-SD increase in pulse pressure the probability of having migraine decreased 13% ( P = 0.005) for men and 14% ( P < 0.0001) for women. In a population-based study of men and women it was found that subjects with migraine had lower pulse pressure, lower systolic BP and higher diastolic BP compared with controls.

Transmissible Infection

Background It is important to have current reliable estimates of the prevalence, correlates and consequences of sexual coercion among a representative sample of Australian adults and to identify changes over time in prevalence and consequences. Methods: Computer-assisted telephone interviews were completed by a representative sample of 20 094 Australian men and women aged 16–69 years. The participation rate among eligible people was 66.2%. Results: Sexual coercion (i.e. being forced or frightened into sexual activity) was reported by 4.2% of men and 22.4% of women. Sexual coercion when aged ≤16 years was reported by 2.0% of men and 11.5% of women. Correlates of sexual coercion were similar for men and women. Those who had been coerced reported greater psychosocial distress, were more likely to smoke, were more anxious about sex and more likely to have acquired a sexually transmissible infection. Few people had talked to others about their experiences of sexual coercion and fewer had talked to a professional. There were no significant differences between the First and Second Australian Study of Health and Relationships in whether men or women had experienced coercion, talked to anyone about this or talked to a counsellor or psychologist. Conclusion: Sexual coercion has detrimental effects on various aspects of people’s lives. It usually occurs at the ages at which people become sexually active. There is a need to reduce the incidence of sexual coercion, better identify experiences of sexual coercion, and provide accessible services to minimise the detrimental effects of sexual coercion.

Abstract This article assesses whether—and to what extent—turnout bias in postelection surveys is reduced by adding a short nonresponse follow-up (NRFU) survey to a mixed-mode survey. Specifically, we examine how the NRFU survey influences response propensities across demographic groups and political factors and whether this affects data quality. We use a rich dataset on validated voter turnout data, collected across two different ballots. In addition to the main survey that comprises computer-assisted telephone interviews (CATI) and web respondents, both studies include a short follow-up mail survey for nonrespondents. The results demonstrate that collecting extra information from additional respondents on so-called “central” questions is worth the effort. In both studies, the NRFU survey substantially increases representativeness with respect to sociodemographic and participation variables. In particular, voters and politically active citizens are more accurately represented in the NRFU survey. This tends to result in better estimates of turnout determinants in the final (combined) sample than is seen from CATI/web respondents only. Moreover, the increase in response rate and the decrease in nonresponse bias comes at almost no price in terms of measurement errors. Vote overreporting is only slightly higher in the mail follow-up survey than in the main CATI/web survey.
