An even protein intake distribution throughout the day has been suggested as necessary to stimulate muscle protein synthesis. This study examined the prevalence and determinants of inadequate protein intake, primary food sources and mealtime distribution of protein in Māori and non-Māori of advanced age. 𝗔𝗶𝗺: To examine the intake, food sources, distribution and adequacy of protein among Māori and non-Māori participants in Life and Living in Advanced Age: A Cohort Study in New Zealand. 𝗠𝗲𝘁𝗵𝗼𝗱𝘀: Dietary intake was assessed in 214 Māori and 360 non-Māori octogenarians with a repeat 24-hour multiple pass recall. Adequate protein intake was determined using the estimated average requirements (EAR) cut-off points of ≤0.75g/kg for women and ≤0.86g/kg for men. Contribution (%) of the primary food groups to protein intake were assessed. Protein intake distribution was determined for the three main meals. A logistic regression model was built to predict meeting the EAR for protein intake per adjusted body weight per day. 𝗥𝗲𝘀𝘂𝗹𝘁𝘀: Total median (IQR) protein intake for women was 0.87 (0.68-1.12) g/kg and for men was 0.97 (0.78-1.21) g/kg. The EAR for protein was not met by a third of both women (30.9%) and men (33.3%). Main food group contributors to protein were beef/veal, fish/seafood, milk, bread and differed by gender and ethnicity. For women and men respectively protein distribution (g/meal) was lowest at breakfast (10.1g and 13.0g), followed by lunch (14.5 and 17.8g) and dinner (23.3 and 34.2). Being a woman and having depressive symptoms were associated with consuming less total protein. Controlling for all other variables the odds of meeting the EAR for protein was higher in participants who had their own teeth or partial dentures (P=0.036). 𝗖𝗼𝗻𝗰𝗹𝘂𝘀𝗶𝗼𝗻𝘀: Among advanced age Māori and non-Māori these findings highlight the prevalence of low protein intake, uneven mealtime protein distribution and importance of dentition for adequate protein intake. en The Author Protein intake, distribution, sources, adequacy and determinants in Māori and non-Māori octogenarians : life and living in advanced age : a cohort study in New Zealand (LiLACS
