This study aimed to estimate the associations between heavy male alcohol use, endorsement of traditional masculine norms and MFIPV perpetration, and test their interaction among Australian men.\n\n\nDesign and setting\nCross‐sectional analysis of nationally representative data from Wave 1 (2013–2014) of the Australian Longitudinal Study on Male Health (Ten to Men).\n\n\nParticipants\nParticipants were 12 284 men who were Australian citizens or permanent residents aged 18 years or older who identified as heterosexual and answered any of the MFIPV items.\n\n\nMeasurements\nThe primary outcome was lifetime MFIPV perpetration assessed through three items on frightening, physically harming or forcing sex on a partner. Predictors included past‐year heavy episodic drinking (HED) and endorsement of masculine norms. Sociodemographics, other drug use, depression, anxiety and sexual performance problems were included as covariates. Multivariable logistic regression models with 95% confidence intervals (CI) were used to examine associations between sociodemographics, specific masculine norms, HED, total masculinity scores and perpetrating MFIPV. An interaction between HED and masculinity on MFIPV was also tested.\n\n\nFindings\nOf the 12 284 men (Mage = 38.3 years), 2947 (23.8%, 95% CI = 22.7–25.0) reported lifetime perpetration of MFIPV, with men aged 30–49 years reporting the highest perpetration rate (26.8%, 95% CI = 24.5–29.1). Higher mean scores on playboy, risk‐taking, self‐reliance, power over women and violence norms were associated with increased odds of reporting MFIPV perpetration, whereas greater scores on emotional control, primacy of work and heterosexual presentation norms appeared protective. Past‐year HED [odds ratio (OR) = 1.24, 95% CI = 1.05–1.48] and greater total masculinity scores (OR = 1.03, 95% CI = 1.01–1.04) were both independently associated with statistically significantly higher odds of reporting lifetime MFIPV perpetration. A statistically significant interaction effect revealed higher total masculinity scores were associated with increased odds of MFIPV perpetration among men with past‐year HED, after adjusting for sociodemographic characteristics and covariates (OR = 1.03, 95% CI = 1.00–1.06, P = 0.035), but not among men who did not engage in HED.\n\n\nConclusions\nAmong Australian men, heavy episodic drinking appears to modify the association between traditional norms of masculinity and reporting male‐to‐female intimate partner violence, with stronger endorsement of traditional masculine norms associated with higher odds of perpetration among men reporting past‐year heavy episodic drinking.\n\n"]
