Methods: A purposive design in combination with a convenience sampling approach was used to recruit 24 women ages 26 to 55 of Malay, Indian, and Chinese descent across 15 university departments in Kuala Lumpur, Malaysia. Audio recordings of the individual semi-structured interviews were transcribed and analyzed using grounded theory.
Results: Women identified two important life transitions, getting married and having children, as particularly influential in changing eating behavior. Women reported a desire to eat healthier that was in tension with pressures to cater to the taste preferences of their household members and to accommodate their work schedules. Persistent social norms of eating in group settings and difficulty in accessing foods perceived as nutritious were reported as barriers to changing individual eating behavior. Regardless of education level and marital status, women agreed that the act of eating was closely connected with cultural values and embodied important meanings that took precedence over eating as a health-promoting behavior. While all participants expressed a desire to eat healthier, many reported limited confidence in their ability to consistently give up familiar and tasty foods for healthier alternatives. Shifts in eating behavior such as trying new healthy recipes and adopting a more restrictive diet were reported as most feasible and personally applicable after learning about a family member's declining health.
Conclusions: In this urban, multiethnic population, increasing the accessibility of nutritious foods and changing cultural perceptions of the relationship between food and nutrition may be important for enabling healthy eating behaviors.

DESIGN: A grounded theory approach and semistructured interviews.
SETTING: A large university in metropolitan Malaysia.
PARTICIPANTS: Twenty-four female employees purposively recruited to vary in ethnicity, body mass index, age, and marital status via convenience sampling.
PHENOMENON OF INTEREST: Perceptions of sociocultural influences on healthy eating behavior among working women.
ANALYSIS: Researchers audio-recorded interviews and analyzed verbatim transcripts.
RESULTS: Working women shared a desire to eat a healthier, more balanced diet by reducing processed food consumption through home-cooked meals. Participants described aspects of their living situations and cultural values about food that made it seem impossible to change their diets. Living with other people limited their ability to cook the food they wanted to eat. In addition, unspoken rules about communal eating in Malaysia, such as not refusing food and not wasting food, prevented working women from practicing healthy eating.
CONCLUSIONS AND IMPLICATIONS: In this population of working women in metropolitan Malaysia, experiences of time scarcity and limited sociocultural support for behavior change were major barriers to healthy eating. Interventions could prioritize leveraging these realities about food to facilitate environments in which women feel like they have control of their own food intake.
METHODS: We did a systematic review for studies on anal HPV infection in men and a pooled analysis of individual-level data from eligible studies across four groups: HIV-positive men who have sex with men (MSM), HIV-negative MSM, HIV-positive men who have sex with women (MSW), and HIV-negative MSW. Studies were required to inform on type-specific HPV infection (at least HPV16), detected by use of a PCR-based test from anal swabs, HIV status, sexuality (MSM, including those who have sex with men only or also with women, or MSW), and age. Authors of eligible studies with a sample size of 200 participants or more were invited to share deidentified individual-level data on the above four variables. Authors of studies including 40 or more HIV-positive MSW or 40 or more men from Africa (irrespective of HIV status and sexuality) were also invited to share these data. Pooled estimates of anal high-risk HPV (HR-HPV, including HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68), and HSIL or worse (HSIL+), were compared by use of adjusted prevalence ratios (aPRs) from generalised linear models.
FINDINGS: The systematic review identified 93 eligible studies, of which 64 contributed data on 29 900 men to the pooled analysis. Among HIV-negative MSW anal HPV16 prevalence was 1·8% (91 of 5190) and HR-HPV prevalence was 6·9% (345 of 5003); among HIV-positive MSW the prevalences were 8·7% (59 of 682) and 26·9% (179 of 666); among HIV-negative MSM they were 13·7% (1455 of 10 617) and 41·2% (3798 of 9215), and among HIV-positive MSM 28·5% (3819 of 13 411) and 74·3% (8765 of 11 803). In HIV-positive MSM, HPV16 prevalence was 5·6% (two of 36) among those age 15-18 years and 28·8% (141 of 490) among those age 23-24 years (ptrend=0·0091); prevalence was 31·7% (1057 of 3337) among those age 25-34 years and 22·8% (451 of 1979) among those age 55 and older (ptrend<0·0001). HPV16 prevalence in HIV-negative MSM was 6·7% (15 of 223) among those age 15-18 and 13·9% (166 of 1192) among those age 23-24 years (ptrend=0·0076); the prevalence plateaued thereafter (ptrend=0·72). Similar age-specific patterns were observed for HR-HPV. No significant differences for HPV16 or HR-HPV were found by age for either HIV-positive or HIV-negative MSW. HSIL+ detection ranged from 7·5% (12 of 160) to 54·5% (61 of 112) in HIV-positive MSM; after adjustment for heterogeneity, HIV was a significant predictor of HSIL+ (aPR 1·54, 95% CI 1·36-1·73), HPV16-positive HSIL+ (1·66, 1·36-2·03), and HSIL+ in HPV16-positive MSM (1·19, 1·04-1·37). Among HPV16-positive MSM, HSIL+ prevalence increased with age.
INTERPRETATION: High anal HPV prevalence among young HIV-positive and HIV-negative MSM highlights the benefits of gender-neutral HPV vaccination before sexual activity over catch-up vaccination. HIV-positive MSM are a priority for anal cancer screening research and initiatives targeting HPV16-positive HSIL+.
