- Background and aim: Health status is an independent predictor of mortality, morbidity and functioning in older people. The present study was designed to evaluate the link between socioeconomic status (SES), physical activity (PA), independence (I) and the health status (HS) of older people in Iran, using structural equation modelling. Methods: Using computerized randomly selection, a representative sample of 851 75-year-olds living in Tehran (2007-2008), Iran, was included. Participants answered questions regarding indicators of HS, SES and also PA and I through interviews. Both measurement and conceptual models of our hypotheses were tested using Mplus 5. Maximum-likelihood estimation with robust standard errors (MLR estimator), chisquare tests, the goodness of fit index (and degrees of freedom), as well as the Comparative Fit Index (CFI), and the Root Mean Square Error of Approximation (RSMEA) were used to evaluate the model fit. Results: The measurement model yielded a reasonable fit to the data, chi(2) = 110.93, df = 38; CFI = 0.97; RMSEA = 0.047, with 90% C.I. = 0.037-0.058. The model fit for the conceptual model was acceptable; chi(2) = 271.64, df = 39; CFI = 0.91; RMSEA = 0.084, with 90% C.I. = 0.074-0.093. SES itself was not a direct predictor of HS (beta = 0.13, p = 0.059) but it was a predictor of HS either through affecting PA (beta = 0.31, p < 0.001) or I (beta = 0.57, p < 0.001). Conclusion: Socioeconomic status appeared to influence health status, not directly but through mediating some behavioral and self-confidence aspects including physical activity and independence in ADL.

- Purpose. To translate the Swedish version of the Falls Efficacy Scale (FES), the FES(S), into Persian, and to determine reliability and validity of the scale to be used for Persian speaking elderly people. Method. The 'forward-backward' procedure was applied to translate the FES(S) into Persian. A methodological study was then carried out to determine the psychometric properties of the Persian version of the scale. Eighty-one community-dwelling elderly persons (≥65 years) were included. Results. Both reliability and validity of the Persian FES(S) were found to be acceptable (Cronbach's α = 0.75, interclass correlation coefficients = 0.99, p < 0.001 and standard errors of measurements = 1.82). Low to moderate negative correlations of the total score of the scale with the age of the participants and number of falls in the past year were shown. There were also low to moderate correlations between the Persian FES(S) score and the Mini-Mental State Examination score, duration of walks and physical fitness. The participants who took a daily walk, felt healthy, reported no general tiredness and who had had no fall during the past year rated their self-efficacy higher than did their peers. Conclusions. The present study verified that the Persian FES(S) is a culturally relevant, valid and reliable tool for measuring self-perceived confidence in Iranian older adults.

- An active life style can postpone the aging process, prevent many aspects of functional decline and improve health and quality of life. The aim of this study was to compare elderly people who walked at least 30 min a day with others who walked less, from a gender perspective, regarding perceived health and fitness, physiological capacity and functional performance. A representative sample of 75-year-olds born 1932-33 and living in Tehran, in 2007-2008 was included by randomly selecting 1100 subjects from the latest Iranian census records (1996) by the Statistical Centre of Iran using computerized methods. Participants answered questions regarding health status and physical activity and performed functional tests. Better results for Walkers were observed in most subjective and objective outcome measures. Walkers were less likely to feel generally tired, more likely to have better physical fitness and to have the maximum score on the Falls Efficacy Scale, less likely to feel unstable during walking outdoors and less likely to be dependent or unsafe in ADL. Walkers of both genders performed better in the following tests: chair stand, one leg stance, maximal walking speed and six min walking. The difference between Walkers and Non-Walkers was greater in men. In general, older women and men who walked at least 30 min daily/almost daily showed better results in most health-related outcomes, ADL and functional performance than people who walked less. This study showed gender differences in the level of physical activity and functioning that must be taken into account when planning intervention programs. (C) 2013 Elsevier Ireland Ltd.

- BackgroundEffects of zinc with and without iron co-supplementation on child development are uncertain therefore the aims of this systematic review were to explore whether supplementation with zinc alone and zinc with iron in children aged 0–5 years old have beneficial or adverse effects on their mental and motor development.MethodWe searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, Web of Science and Scopus until July 2020 and included randomized controlled trials, which assessed effects of zinc supplementation with and without iron in children less than 5 years old on mental and motor development. Data were pooled by random effects model and the Standardized Mean Differences (SMDs) with 95% confidence interval were estimated. The heterogeneity was assessed by I2.ResultsTwenty-five studies with 11,559 participants were eligible to be included in this systematic review. Meta-analysis was conducted with eight articles that used Bayley Scales of Infant and Toddler Development II. We concluded that zinc alone and zinc with iron co-supplementation do not have beneficial or adverse effect on child mental and motor development at 6 and 12 months of age with low to moderate quality of the evidence. Furthermore, Zinc supplementation does not have any long term effect on child development in preschool and school age children.ConclusionMost included studies did not show the efficacy of zinc with and without iron co-supplementation on child mental and motor development up to 9 years old age. Further Randomized Controlled Trials (RCTs) need to be taken into considerations the context-based differences between countries with special focus on socio-economic differences.
