WEDNESDAY, Nov. 28, 2018 (HealthDay News) — For very old adults, higher protein intake is associated with better disability trajectories, according to a study published online Nov. 1 in the Journal of the American Geriatrics Society<\/i>.<\/p>\n
Nuno Mendon\u00e7a, R.D., Ph.D., from Newcastle University in the United Kingdom, and colleagues examined whether protein intake is associated with better disability trajectories in 722 community-dwelling older adults aged 85 years at baseline. Two 24-hour multiple-pass recalls were used to estimate protein intake. Disability was assessed as difficulty performing 17 activities of daily living.<\/p>\n
The researchers identified four distinct disability trajectories: constant very low (AT1), mild (AT2), moderate, and severe (AT4). In models adjusted for selected covariates, each unit increase in protein per kilogram of adjusted body weight per day (aBW\/d) was correlated with greater odds of AT1 and AT2 than AT4 (odds ratios, 7.97 and 3.28, respectively) during five years. Participants with protein intake of at least 1 g\/kg aBW\/d were more likely to be in AT1 or AT2 than AT4 (odds ratios, 3.65 and 2.12, respectively).<\/p>\n
“The results support the consensus statements that protein intake in older adults should approximate 1.0 to 1.2 g\/kg BW\/d, which is within the acceptable macronutrient distribution range,” the authors write.<\/p>\n
