AIDS has become a major cause of death in Tanzania and young people represent the most vulnerable group. Recent HIV prevalence data showed that young women are more likely than young men to become infected. This paper examined commonalties and differences in the sociodemographic and ideational predictors of condom use among young men and women in Tanzania. The data derive from a 2004 sample sur...

The effects of aging on motoneuron firing rates and muscle contractile properties were studied in tibialis anterior muscle by comparing results from six young (20.8 +/- 0.8 yr) and six old men (82.0 +/- 1.7 yr). For each subject, data were collected from repeated tests over a 2-wk period. Contractile tests included maximal voluntary contraction (MVC) with twitch interpolation and stimulated twi...

Maximal force production per unit of muscle mass (muscle quality, or MQ) has been used to describe the relative contribution of non-muscle-mass components to the changes in strength with age and strength training (ST). To compare the influence of age and gender on MQ response to ST and detraining, 11 young men (20-30 years), nine young women (20-30 years), 11 older men (65-75 years), and 11 old...

CONTEXT Recently, increasing interest has been shown in men's reproductive health, sexual behaviour and use of contraception. As the majority of sexual health service clients are female, however, little research has been done on the characteristics and needs of male clients. OBJECTIVE Using data from focus group discussions, this paper considers whether young men need sexual health services, ...

The article examines the use of newer, interactive information and communication technologies (ICTs) in young men's health promotion (HP), drawing on gender theory, HP research and evidence on young men's Internet usage. The focus is on highlighting an agenda for research in terms of emerging issues. New forms of social media ICT (for example 'web 2'-based on-line social networking sites, micro...

BACKGROUND Aboriginal adolescents are more likely to become pregnant and contract an STI than other Canadian adolescents. This study provides some of the first data on factors associated with these outcomes among Aboriginal adolescents. METHODS A secondary analysis was conducted using 2003 data from a large cross-sectional survey of British Columbia secondary school students. 445 young women ...

OBJECTIVES We sought to study gender differences in young adult smoking declines and enrollment in populationwide cessation services. METHODS The New York City (NYC) Department of Health and Mental Hygiene implemented populationwide cessation programs to distribute free nicotine replacement therapy (NRT); demographic data were collected from enrollees. Smoking prevalence was assessed using da...

We determined the independent and interactive influences of aging and habitual endurance exercise on calf venous compliance in humans. We tested the hypotheses that calf venous compliance is 1) reduced with age in sedentary and endurance-trained men, and 2) elevated in young and older endurance-trained compared with age-matched sedentary men. We studied 8 young (28 +/- 1 yr) and 8 older (65 +/-...
