The effect of nutrition on quality of life (QOL) was measured in a randomized clinical trial designed to assess the effects of two different medically prescribed diets on cardiovascular risk factors and QOL in persons (n = 560) with either hypertension, hyperlipidemia, diabetes, or any combination of these conditions. One diet consisted of a nutrient-fortified, prepared meal plan (CCNW) formulated to achieve a macronutrient content of 15-20% fat, 15-20% protein, and 55-60% carbohydrate and a micronutrient content that met or exceeded the RDA for 22 vitamins and minerals. The other diet was matched for macronutrient content and was self-selected (SS) based on American Dietetic Association exchange lists. A battery of generic and nutrition-specific instruments was used to measure QOL. The results show that both the CCNW diet group and the SS diet group had statistically significant improvements over the 10-week intervention for all QOL instruments (p < 0.0001). The CCNW group had greater improvements than the SS diet group in daily activities and work performance (p < 0.05), as well as nutritional health perceptions (p < 0.001). There were significant correlations between QOL scores and improvements in risk factor profiles. Of the instruments tested, Nutritional Health Perception scores were most closely correlated with each of the risk factors, as well as with adherence to Step I and Step II dietary guidelines. Overall, the results show that nutrition can have a robust effect on QOL. Of the two diet conditions, the CCNW group had the most favorable outcomes for QOL as well as adherence and risk factor reduction.
