Article Abstract
There is an inverse association between bioactive compounds intake and disease risk. The knowledge of its consumption according to socio-economic strata is important, which allows identification of potential intervention targets. Thus, we aimed to investigate bioactive compounds intake according to income level in Brazilian population. Data were obtained from the Brazilian Household Budget Survey, a cross-sectional survey which included data on individual food intake of 34,003 subjects aged 10 years and over collected using two 24-h dietary records. Polyphenol and carotenoid content of foods was identified using published databases. Total polyphenol and carotenoid intake were determined according to per capita income, as well as main food sources. Total polyphenols and flavonoids intake increased with income level, and subjects with lower income showed higher phenolic acids intake than individuals in highest income (p = 0.0001). Total carotenoids and classes intake (with exception to β-cryptoxanthin and zeaxanthin) were higher among subjects in highest income quartile, compared to the lowest quartile (p = 0.0001). Coffee was major source to total polyphenols and phenolic acids intake, and orange juice was main flavonoid provider in individuals from all income levels. In the upper income quartile, total carotenoid was supplied mainly by tomato and kale, and fruits had important contribution to carotenoid intake in the lowest income quartile. There is important influence of income level on diet quality regarding intake of foods with bioactive compounds, and individuals with lower income may experience lower quality diets due to less availability of foods with bioactive compounds.
Introduction: Micronutrient malnutrition remains a huge public health problem, with the main issues lying with the lack of diet diversity, either lack or less of animal products, sparse amount of fruits and vegetables. Fruits are a very good source of vitamins and minerals to help in the growth and development of the child. There are a lot of implementation hurdles at the ground level.
Material stocks of infrastructure, buildings, and machinery are the biophysical basis of production and consumption. They are a crucial lever for resource efficiency and a sustainable circular economy. While material stock research has proliferated over the last years, most studies investigated specific materials or end-uses, usually not embedded into an economy-wide perspective.
Background: Respiratory infectious diseases (RIDs) are a global public health problem, characterized by strong infectivity, high transmissibility, and a high incidence in the population. This study aimed to explore RID prevention behaviors among older adults and analyze their influencing factors.
Methods: A cross-sectional study was conducted to examine RID prevention behaviors among 2219 Chinese older adults.
Background: Understanding the financial burden of smoking on households is crucial for developing effective strategies and policies to reduce smoking and mitigate its impact on household health.
Aim: To investigate the relationship between smoking and catastrophic health expenditure in Türkiye.
Methods: This cross-sectional study used microdata from household budget surveys conducted by the Turkish Statistical Institute in 2015 and 2019.
Purpose: This study aimed to identify social isolation latent profiles and analyze the specific mechanisms in which social support, resilience, and posttraumatic growth associated social isolation from the perspective of positive psychology. Suggestions were offered to improve the mental health status of postoperative enterostomy patients with colorectal cancer.
