Cardiovascular disease risk score prediction models for women and its applicability to Asians

Purpose: Although elevated cardiovascular disease (CVD) risk factors are associated with a higher risk of developing heart conditions across all ethnic groups, variations exist between groups in the distribution and association of risk factors, and also risk levels. This study assessed the 10-year predicted risk in a multiethnic cohort of women and compared the differences in risk between Asian and Caucasian women. Methods: Information on demographics, medical conditions and treatment, smoking behavior, dietary behavior, and exercise patterns were collected. Physical measurements were also taken. The 10-year risk was calculated using the Framingham model, SCORE (Systematic COronary Risk Evaluation) risk chart for low risk and high risk regions, the general CVD, and simplified general CVD risk score models in 4,354 females aged 20–69 years with no heart disease, diabetes, or stroke at baseline from the third Australian Risk Factor Prevalence Study. Country of birth was used as a surrogate for ethnicity. Nonparametric statistics were used to compare risk levels between ethnic groups. Results: Asian women generally had lower risk of CVD when compared to Caucasian women. The 10-year predicted risk was, however, similar between Asian and Australian women, for some models. These findings were consistent with Australian CVD prevalence. Conclusion: In summary, ethnicity needs to be incorporated into CVD risk assessment. Australian standards used to quantify risk and treat women could be applied to Asians in the interim. The SCORE risk chart for low-risk regions and Framingham risk score model for incidence are recommended. The inclusion of other relevant risk variables such as obesity, poor diet/nutrition, and low levels of physical activity may improve risk estimation

Process evaluation of a peer-led antenatal breastfeeding class for fathers: perceptions of facilitators and participants

Background: The Parent Infant Feeding Initiative (PIFI) was a factorial, randomised controlled trial that aimed to prolong exclusive breastfeeding by targeting expecting fathers. One of the intervention strategies evaluated was a father-focused breastfeeding class facilitated by a male peer facilitator. The aim of this mixed-methods descriptive study was to 1) evaluate the feedback provided from participants of the class and 2) explore the motivations and experiences of volunteer male peer facilitators trained to deliver the class. Methods: Father-focused breastfeeding antenatal (FFAB) classes were conducted in six Western Australian hospitals between August 2015 and December 2016. Following each peer facilitated FFAB class, expecting father participants completed an evaluation form to assess their satisfaction with the format, facilitation and content, in addition to whether their expectations and confidence to manage breastfeeding problems had changed. Feedback to open-ended questions was analysed using content analysis to identify learnings and suggestions for improvements. At the completion of PIFI, individual telephone interviews were undertaken with 14 peer facilitators to gain insight into their motivations for volunteering and experiences of conducting the classes. Transcripts from interviews were analysed using Braun and Clarke’s six phases for thematic analysis. Results: Participant evaluation forms were completed by 678 of the 697 father participants (98%). Overall satisfaction with class format, facilitation and content was high with 90% or more of fathers either strongly agreeing or agreeing with each positively-phrased evaluation item. Class participants enjoyed interacting with other fathers, appreciated validation of their role, were not always aware of the importance of breastfeeding or potential difficulties, valued the anticipatory guidance around what to expect in the early weeks of parenting and appreciated learning practical breastfeeding support strategies. Peer facilitators indicated they felt well prepared and supported to conduct FFAB classes. Analysis of interview transcripts revealed common experiences of the peer facilitators incorporating four themes: ‘Highlights of being a facilitator’, ‘Challenges’, ‘Mourning the project completion’ and ‘Satisfaction with training and support’. Conclusion: Father-focused breastfeeding classes supported by volunteer male peer facilitators are a feasible and acceptable way of engaging fathers as breastfeeding supporters.

Methodological challenges in collecting social and behavioural data regarding the HIV epidemic among gay and other men who have sex with men in Australia

©2014 Zablotska et al. Background: Behavioural surveillance and research among gay and other men who have sex with men (GMSM) commonly relies on non-random recruitment approaches. Methodological challenges limit their ability to accurately represent the population of adult GMSM. We compared the social and behavioural profiles of GMSM recruited via venue-based, online, and respondent-driven sampling (RDS) and discussed their utility for behavioural surveillance. Methods: Data from four studies were selected to reflect each recruitment method. We compared demographic characteristics and the prevalence of key indicators including sexual and HIV testing practices obtained from samples recruited through different methods, and population estimates from respondent-driven sampling partition analysis. Results: Overall, the socio-demographic profile of GMSM was similar across samples, with some differences observed in age and sexual identification. Men recruited through time-location sampling appeared more connected to the gay community, reported a greater number of sexual partners, but engaged in less unprotected anal intercourse with regular (UAIR) or casual partners (UAIC). The RDS sample overestimated the proportion of HIV-positive men and appeared to recruit men with an overall higher number of sexual partners. A single-website survey recruited a sample with characteristics which differed considerably from the population estimates with regards to age, ethnically diversity and behaviour. Data acquired through time-location sampling underestimated the rates of UAIR and UAIC, while RDS and online sampling both generated samples that underestimated UAIR. Simulated composite samples combining recruits from time-location and multi-website online sampling may produce characteristics more consistent with the population estimates, particularly with regards to sexual practices. Conclusion: Respondent-driven sampling produced the sample that was most consistent to population estimates, but this methodology is complex and logistically demanding. Time-location and online recruitment are more cost-effective and easier to implement; using these approaches in combination may offer the potential to recruit a more representative sample of GMSM

Towards a more unified definition of health promotion

Issues addressed: Health promotion continues to be constrained by the lack of a consistent, clear and useable definition. Discussion: The authors reviewed definitions of health promotion from the international literature and cross-referenced them with the national health promotion competencies and current health promotion practice. The key elements of the most widely used concepts of health promotion have been incorporated into a single definition. A case study has been used to illustrate its practical nature. So what? A clear definition is essential for providing guidance to the scope and nature of health promotion for health promotion practitioners, researchers and their clients. The definition can facilitate planning, implementing and evaluating interventions. In addition, the credibility of health promotion as a professional entity will benefit from a definition that describes uniformity of action

Impact of a Face-To-Face Versus Smartphone App Versus Combined Breastfeeding Intervention Targeting Fathers: Randomized Controlled Trial.

BACKGROUND: Despite the recognized health and economic benefits of exclusive breastfeeding, few Australian infants are exclusively breastfed beyond 5 months of age. Social support for breastfeeding, in particular the support of an infant's father, has been identified as a crucial element for successful breastfeeding. OBJECTIVE: The objective of this study was to determine the effectiveness of various father-focused breastfeeding interventions in terms of key infant feeding outcomes. METHODS: The study was a 4-arm, factorial, randomized controlled trial conducted in Perth, Australia. The trial arms included a control group and 3 interventions, consisting of a face-to-face father-focused antenatal breastfeeding class facilitated by a male peer facilitator; Milk Man, a breastfeeding smartphone app designed specifically for fathers; and a combination of both interventions. Expecting couples were recruited from hospital-based antenatal classes and block randomized to 1 of the 4 arms. Each partner completed surveys at recruitment and at 6 weeks and 26 weeks postpartum. Primary outcomes were duration of exclusive and any breastfeeding. Secondary outcomes included age of introduction of formula and complementary foods, maternal breastfeeding self-efficacy, and partner postpartum support. RESULTS: A total of 1426 couples were recruited from public (443/1426, 31.1%) and private (983/1426, 68.9%) hospitals. Of these, 76.6% (1092/1426) of fathers completed the baseline questionnaire, 58.6% (836/1426) completed the 6-week follow-up questionnaire, and 49.2% (702/1426) completed the 26-week follow-up questionnaire. The average age of fathers who completed the baseline questionnaire was 33.6 (SD 5.2) years; the majority were born in Australia (76.4%) and had attended university (61.8%). There were no significant differences between the control and any of the intervention groups in any of the infant feeding outcomes or level of breastfeeding self-efficacy and postpartum partner support reported by mothers. CONCLUSIONS: This study did not demonstrate that any intervention was superior to another or that any intervention was inferior to the standard care delivered in routine antenatal classes. Further studies are needed to test the effectiveness of these interventions in more socioeconomically diverse populations that are likely to benefit most from additional partner supports.

The acceptability of different HIV testing approaches: cross-sectional study among GMSM in Australia

Background: We explored the attitudes of Australian gay and other men who have sex with men (GMSM) about the current standard-of-care (non-rapid tests at healthcare settings) and alternative approaches (rapid tests and testing in non-healthcare settings) to better understand the acceptability of alternative testing approaches. Methods: The Contemporary Norms in Networks and Communities of GMSM study enrolled GMSM in Sydney, Melbourne and Perth in 2011–2012 using peer referrals. We explored the self-reported preferences for testing: rapid versus non-rapid and in non-healthcare settings (community-based or home-based testing) versus in healthcare settings, and examined factors associated with preferences for these approaches. Analyses of associations used standard univariate and age-adjusted logistic regression models. Results: Among 827 sexually active non-HIV-positive participants, 89% had been tested for HIV. Most preferred by participants was home rapid testing (46%), followed by standard-of-care (23%) and rapid testing in healthcare (20%) or community settings (7%). About 73% of participants preferred rapid over non-rapid testing, and 56% preferred testing in non-healthcare settings rather than in healthcare settings. Preference for rapid testing was associated with being fully employed (adjusted OR (aOR): 1.81; 95% CI 1.16 to 2.82), managerial/professional occupation (aOR: 2.03; 95% CI 1.19 to 3.46) and engaging in unprotected anal intercourse with casual partners (aOR: 1.89; 95% CI 1.29 to 2.78). The same factors were associated with preference for testing in non-healthcare settings. Conclusions: Australian GMSM prefer alternative testing approaches, possibly due to their convenience. The availability of new testing approaches may provide more options for GMSM at risk for HIV infection, improve access to HIV testing and potentially increase HIV testing rates

The Ocean Decade-Opportunities for Oceans and Human Health Programs to Contribute to Public Health.

The COVID-19 pandemic reminds us that our health is vulnerable to immediate threats emerging from the ecosystems we inhabit. More insidious global threats include the increasingly overt consequences of climate change, biodiversity loss, and pollution. As the largest connected ecosystem on Earth, the global ocean exerts a greater influence than any other on our climate and weather, affecting global food production and international trade. Much more importantly, human health is intricately linked to “ocean health.”1,2 The United Nations has announced the Decade of Ocean Science for Sustainable Development from 2021 to 2030 (http://bit.ly/3kePT9f). Public health and medical professionals should embrace this timely opportunity to transform the way we interact with our seas. We call for a revitalized, inclusive endeavor to repair the damage we have done during our careless past and to protect the myriad benefits available in the future. Making amends will necessitate bringing together ocean researchers, health professionals, coastal communities, policymakers, and other stakeholders to work on delivering a resilient, sustainable ocean that fosters improvements in public health

The Power of Peers: Why Some Students Bully Others to Conform

Utilizing an interactionist perspective, two associated sensitizing constructs, and a combination of social psychological theory, this article reports on the influence of the peer group on individual perceptions, and its impact on initiation and persistence of bullying. The specific research question, “How does the need to conform with peers and the peer group influence the initiation and persistence of bullying others?” is investigated. Semistructured, one-on-one interviews with a purposive sample of 51 Grade 7 students (aged 12 years) were conducted during school time to investigate factors that influence students to bully others and what might help them to stop. Emerging from the theme of peer group was the need for belonging and group status, in particular social norms or the need to conform, which was influential when students described why they initiated and persisted with bullying others. The influence of labeling, the group process, and the aspiration to be like others within their group emerged as key constructs. The implications of these data for schools will be described and recommendations made
