A Food Insecurity Systematic Review: Experience from Malaysia.

Living free from hunger is a basic human right. However, some communities still experience household food insecurity. This systematic literature review explored different aspects of household food insecurity in Malaysia including vulnerable groups, prevalence, risk factors, coping strategies, and the consequences of food insecurity. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Thirty-three relevant articles were selected from scientific databases such as CINAHL, Pubmed and Google Scholar, scrutiny of reference lists, and personal communication with experts in the field. The prevalence of household food insecurity in Malaysia was unexpectedly reported as high, with affected groups including Orang Asli, low-income household/welfare-recipient households, university students, and the elderly. Demographic risk factors and socioeconomic characteristics included larger household, living in poverty, and low education. Coping strategies were practices to increase the accessibility of food in their households. Consequences of household food insecurity included psychological, dietary (macro- and micronutrient intakes), nutritional status, and health impacts. In conclusion, this review confirmed that household food insecurity in Malaysia continues to exist. Nevertheless, extensive and active investigations are encouraged to obtain a more holistic and comprehensive picture pertaining to household food security in Malaysia.

Estimation of Flavonoid Intake in Older Australians: Secondary Data Analysis of the Blue Mountains Eye Study.

Flavonoids, consumed in plant-based foods, have been linked to risk reduction of cancers, cardiovascular, and neurodegenerative diseases. The paucity of information on dietary sources and quantities of flavonoid intake in older adults limits interpretation of epidemiological studies that link flavonoid intake with health outcomes in this population. It was our aim to describe total flavonoid intake, including flavonoid subclasses, in older Australians and to identify rich and commonly consumed sources of flavonoids in this age group. Twelve days of weighed food record dietary data from a subsample of the Blue Mountains Eye Study baseline cohort study of older Australians (n = 79) was analyzed using the US Department of Agriculture flavonoid database. Mean intake of flavonoids was estimated to be 683 mg/day (SD = 507) of which flavan-3-ols contributed 92%, followed by flavonols (4%), flavanones (3%), and flavones (<1%). Black tea was the major flavonoid source, providing 89% of total flavonoid intake. No differences in intake between genders were identified. Dietary intake of flavonoids and flavonoid subclasses in older Australians is similar to the one other estimation of intake in Australian older adults and confirms the types of foods that contribute to flavonoid intake among this sample of older Australians.

Adherence to dietary guidelines and the 10-year cumulative incidence of visual impairment: the Blue Mountains Eye Study.

PURPOSE: To assess whether adherence to dietary guidelines at baseline is associated with the incidence of visual impairment among older persons after 10 years. DESIGN: A population-based cohort of 3654 participants of the Blue Mountains Eye Study were examined at baseline and were reexamined after 5 and 10 years. METHODS: The incidence of visual impairment was defined as best-corrected visual acuity (VA)<20/40 at follow-up in 1 or both eyes. Dietary information was obtained at baseline using a validated food frequency questionnaire (FFQ). Total Diet Score (TDS) was calculated based on the Australian diet quality index. TDS includes components of diet quality; poor dietary habits; and energy balance. Discrete logistic regression models with time-dependant outcome variables were used to calculate hazard risk ratios (HR) and 95% confidence intervals (CI) associated with incidence of visual impairment for each unit/quartile increase in TDS, adjusting for potential confounders. RESULTS: Of the 3654 baseline participants, 1963 had up to 10 years follow-up with completed FFQs. With each unit increase in TDS, the risk of visual impairment decreased (HR 0.94, 95% CI 0.88-1.00). The risk of developing visual impairment was lower among persons in the highest compared to the lowest TDS quartile (HR 0.71, 95% CI 0.47-1.05). This association was significant among persons aged 65+ years (HR 0.63, 95% CI 0.38-0.98) but not those aged <65 years (HR 0.95, 95% CI 0.46-1.97). CONCLUSIONS: Compliance to dietary guidelines was associated with a decreased long-term risk of visual impairment in this sample of Australians aged 65+ years.
