Abstract
BACKGROUND: The oldest old (85+) are the fastest growing population segment in New Zealand. Cardiovascular disease (CVD) is the main cause of death and is associated with various risk factors including risk of undernutrition. OBJECTIVES: To determine if there is an association between CVD and nutrition risk in advanced age. SETTING: Three North Island locations (rural and urban areas) in New Zealand. PARTICIPANTS: 108 participants aged 85 years (75-79 for Maori). MEASUREMENTS: Comprehensive health assessments were undertaken. Clinically manifest CVD was pre-defined and ascertained from interviews and hospitalisation records. Nutrition risk was assessed using a validated questionnaire-Seniors in the Community: Risk evaluation for eating and nutrition, Version II (SCREEN II). RESULTS: 72 participants (67%) had CVD (49% men); 52% of participants had a SCREEN II score < 50. Those with CVD had lower HDL level [median(IQR)] [1.4(0.7) vs. 1.6(0.6)] (p=0.041), and higher waist circumference [97.5(19.1) vs. 89.3(20.6)] (p=0.043) compared to those without CVD. Those with CVD were at no greater nutrition risk than those without CVD (SCREEN II score: [49(7) vs. 51(10)] (p=0.365). Using logistic regression controlling for confounders, SCREEN II scores trended towards an inverse association with CVD (p=0.10). CONCLUSION: Two thirds of the study participants had CVD and half were at risk of undernutrition. Nutrition risk was mildly associated with CVD. This study provides further evidence that those in advanced age are at risk of undernutrition. Further research is needed to establish how the causes and consequences of CVD are related to nutrition risk.
