Sleep complaints and risk factors for excessive daytime sleepiness in adult males in Northern Ireland

The prevalence of sleep complaints in Northern Ireland is unknown. Sleep disruption can result in excessive daytime sleepiness (EDS), with significant socioeconomic consequences. The aim of this study was to assess the prevalence of sleep complaints and to determine risk factors for EDS in a Northern Irish community. From an urban and rural community of 499 111 people, a random sample of 3391 adult men were sent a questionnaire by mail. Questions were asked regarding sleep, EDS and medical history. There were 2364 completed questionnaires returned (response rate 70%). The mean age of respondents was 46.0 years (range 18-91 years). 26.7% of men were not satisfied with their usual night's sleep and 68% of men woke up at least once during the night. Based on pre-defined criteria, 24.6% of the population had insomnia and 19.8% had EDS. The strongest risk factor identified for EDS was a history of snoring loudly (odds ratio 2.62; 95% CI 1.82-3.77). Other risk factors included ankle swelling, feeling sad or depressed stopping sleep, experiencing vivid dreams while falling asleep, waking up feeling unrefreshed and age > 35 years. The prevalence rates of sleep complaints and EDS in this community-based study is high, although this does depend directly on the criteria used to define insomnia and EDS. Recognition of risk factors for EDS may help to identify and treat those affected.

Adolescent males experience of the counselling process

This study examines 11 adolescent males' self-reports of their experiences of 23 counselling sessions to identify what they found helpful and unhelpful during key moments in the therapeutic process. The findings suggest that the experiences of the adolescent males in this study are similar in many ways to the to the reported experiences of adults in counselling. In particular, the experience of emotional support and relief appears to be highly significant for adolescent males, who give significantly lesser importance to cognitive task factors.

Testosterone levels in dominant sociable males are lower than in solitary roamers: Physiological differences between three male reproductive tactics in a sociably flexible mammal

The relative plasticity hypothesis predicts that alternative tactics are associated with changes in steroid hormone levels. In species with alternative male reproductive tactics, the highest androgen levels have usually been reported in dominant males. However, in sociable species, dominant males show amicable behaviors to gain access to females, which might conflict with high testosterone levels. We compared testosterone, corticosterone, and resting metabolic rate in male striped mice (Rhabdomys pumilio) following a conditional strategy with three different reproductive tactics: (i) philopatric group-living males, (ii) solitary-living roamers, (iii) dominant but sociable group-living territorial breeders. Philopatrics had the lowest testosterone but highest corticosterone levels, suggesting that they make the best of a bad job. Dominant territorial breeders had lower testosterone levels than roamers, which have a lower competitive status. Roamers had the highest testosterone levels, which might promote risky behavior, such as invading territories defended by territorial males. Roamers also had lower resting metabolic rates than either type of group-living males. Our results suggest that dominant males' testosterone levels reflect a trade-off between low testosterone amicable behavior and high testosterone dominance behavior.

Conservation genetics of Neotropical pollinators revisited: microsatellite analysis suggests that diploid males are rare in orchid bees

Allozyme analyses have suggested that Neotropical orchid bee (Euglossini) pollinators are vulnerable because of putative high frequencies of diploid males, a result of loss of sex allele diversity in small hymenopteran populations with single locus complementary sex determination. Our analysis of 1010 males from 27 species of euglossine bees sampled across the Neotropics at 2-11 polymorphic microsatellite loci revealed only 5 diploid males at an overall frequency of 0.005 (95% CIs 0.002-0.010); errors through genetic non-detection of diploid males were likely small. In contrast to allozyme-based studies, we detected very weak or insignificant population genetic structure, even for a pair of populations >500 km apart, possibly accounting for low diploid male frequencies. Technical flaws in previous allozyme-based analyses have probably led to considerable overestimation of diploid male production in orchid bees. Other factors may have a more immediate impact on population persistence than the genetic load imposed by diploid males on these important Neotropical pollinators.

Posting Incognito ... Males with Eating Problems: Online Emotional Expression and Support

Qualitative research in the area of eating disorders (eds) has predominantly focused on females,whilst the experiences of males’ remains poorly understood. due to the secretive nature of eating problems/eds it can be difficult to explore the experiences of males with these problems; however, online support groups/message boards, which are common and popular, provide a non-invasive
forum for researchers to conduct research. This study analyzed naturally occurring discussions on an internet message board dedicated to males and eating problems using content analysis. Two major overarching themes of emotional expression (sharing feelings of disturbed eating attitudes and emotions; being secretive) and support (informational and emotional) were identified. The message board provided a vital support system for this group, suggesting that online message boards may be an important avenue for health professionals to provide information, support, and advice.

HPV vaccine acceptance in males

Background Despite Human Papillomavirus (HPV)’s impact on the health of both sexes, there is debate around the inclusion of males in HPV vaccination programmes. The aim of this scoping review was to synthesize the evidence on vaccine acceptability to males. Given that the vaccine is most effective in adolescent males, vaccine acceptance in parents and health care professionals (HCPs) was also examined. Method A rapid synthesis using specified key words of published systematic reviews into vaccine acceptability in adolescent males, parents and HCPs was conducted. The most common electronic databases were searched including: Medline, EMBASE, PsychINFO, and CINAHL. Results There was variability amongst studies with respect to design and methodological approaches. Despite this there appears to be a positive attitude towards male HPV vaccination from both parents and older males. There is currently insufficient evidence on vaccine acceptance to adolescent males. Understanding the risks involved in HPV acquisition, and receiving a recommendation from a HCP, appear to be the major factors involved in males deciding to be vaccinated. Parents consistently report the importance of a HCP recommendation, yet HCPs (in the US) appear to have a preference for vaccinating older than younger adolescents, and for vaccinating females. Conclusions The absence of an agreed definition of vaccine acceptance leads to a lack of a universally accepted tool for its measurement. This makes comparison of studies difficult. With no established theoretical framework the identification and exploration of factors that influence vaccine uptake can be variable. In addition, acceptance is not indicative of uptake. The majority of studies are cross-sectional which makes the identification of factors that lead to actual vaccine uptake difficult. Prospective, longitudinal studies identifying individuals that acted on vaccine intention should be conducted to identify the factors that mediate the uptake.
