OBJECTIVE To determine the effect of antenatal dietary and lifestyle interventions on health outcomes in overweight and obese pregnant women. DESIGN Multicentre randomised trial. We utilised a central telephone randomisation server, with computer generated schedule, balanced variable blocks, and stratification for parity, body mass index (BMI) category,(More)
BACKGROUND The relationship between lower urinary tract symptoms (LUTS) and common mental health disorders such as depression and anxiety in men remains unclear. Inflammation has recently been identified as an independent risk factor for LUTS and depression. This study aimed to assess the association between depression, anxiety and LUTS, and the moderating(More)
BACKGROUND Obesity is a significant global health problem, with the proportion of women entering pregnancy with a body mass index greater than or equal to 25 kg/m2 approaching 50%. Obesity during pregnancy is associated with a well-recognised increased risk of adverse health outcomes both for the woman and her infant, however there is more limited(More)
BACKGROUND It is commonly held that men delay help seeking because they are ignorant about and disinterested in their health. However, this discussion has not been informed by men's lay perspectives, which have remained almost entirely absent from scholarship relating to men's help seeking practices. METHODS In this qualitative paper, we draw on(More)
OBJECTIVE To identify sociodemographic factors associated with help-seeking behaviour for reproductive health disorders in middle-aged and older Australian men. DESIGN A cross-sectional, population-based, computer-assisted telephone interview exploring sociodemographic factors and general and reproductive health. PARTICIPANTS AND SETTING Analysis of(More)
Evidence from both human and animal studies suggests that gonadal steroids, such as testosterone, exert activational effects on adult spatial behavior. Endogenous testosterone levels decline gradually but variably as men age; it remains to be shown whether these decreases are associated with age-related declines in visuo-spatial performance or constituent(More)
OBJECTIVE To determine whether general practice surveillance for childhood obesity, followed by obesity management across primary and tertiary care settings using a shared care model, improves body mass index and related outcomes in obese children aged 3-10 years. DESIGN Randomised controlled trial. SETTING 22 family practices (35 participating general(More)
BACKGROUND The relationship between reproductive health disorders and lifestyle factors in middle-aged and older men is not clear. The aim of this study is to describe lifestyle and biomedical associations as possible causes of erectile dysfunction (ED), prostate disease (PD), lower urinary tract symptoms (LUTS) and perceived symptoms of androgen deficiency(More)
Psychometric measures of processing speed are strong predictors of cognitive functioning with aging; however, the neurobiological mechanisms underlying this association remain unclear. Recently, the authors reported a negative association between calculated free testosterone levels (cEFT) and processing speed in men aged between 50 and 70 years (Martin,(More)
The relationship between the gonadal steroids, testosterone and estrogen, and individual and group differences in performance on some cognitive tasks remains unclear but sex differences favoring males on some tests of visuo-spatial ability are large and robust. This aim of this review is to assess evidence for both organizational and activational effects of(More)
