Abstract
Background and Aim: High fruit and vegetable intake has been introduced as one of the key factors of healthy diet to prevent chronic disease. This study attempts to explore the fruit and vegetable intake in Arak city and its relationship with demography and socio-economic factors.
Materials and Methods : In this cross sectional study, 660 people in 18 -70 age range were selected with a two-stage cluster sampling and were interviewed for demography and socio – economic questionnaires and a 56- items semi-quantitative food frequency questionnaire to assess fruit and vegetable intake. After univariate analysis, the association of the significant variables with fruit and vegetable intake was also evaluated with multiple linear regression.
Results: In this study, over 60 percent of subjects consumed less than the minimum recommended amount of fruit and vegetable (5 servings or 400 gr a day).The total consumption of fruit and vegetable indicated an inverse significant relationship with age (p =0.04 and β = - 0.02), and a direct significant relationship with economic status (p <0.001and β =0.10). The father's educational level (p =0.005 and β =0.38 for diploma level and p =0.03 and β =0.36 for academic education) and physical activity level (p =0.001 and β =0.03 per hour) were factors associated with fruit consumption. The gender was only associated with vegetable consumption so that women had higher consumption in this study (p =0.03 and β=0.23).
Conclusion: The findings of this study indicate low fruit and vegetable consumption in the population under study. In this study, age, physical activity, and socioeconomic status and fathers’ education were the factors that were significantly associated with fruit and vegetable consumption.

Abstract
Background and Aim: The prevalence of chronic diseases can be reduced by correcting people's food habits. Therefore, the purpose of this study was to assess the explanatory power of the Expectation-Confirmation Model for the intention to continue fruit and vegetable consumption.
Materials and Methods: This descriptive-analytic study included 332 elderly people with a history of receiving health care services from 8 rural health centers and 40 health houses in Abadan city, Iran in the second half of 2015. Data were analyzed by path analysis and the multicolinearity test using LISREL8.8 and SPSS16 software, respectively.
Results: Less than half (48%) of the subjects consumed 1 to 3 servings of fruit and vegetable daily. The model used could explain 79% of the intention to continue fruit and vegetable consumption. Analysis of the data also showed positive associations between the intention to continue fruit and vegetable consumption and the following variables: self-efficacy (β = 0.09, P <0.01), perceived ease of use (β = 0.15, P <0.01), perceived benefits (β = 0.37, P <0.01), and satisfaction (β = 0.35, P <0.01); however, the perceived barriers had an inverse relationship with that intention (β=-0/2, P <0.01). From among the constructs of the mode, perceived benefits were the most effective factor influencing the intention to continue fruit and vegetable consumption (β=0.85, P <0.01).
Conclusion: The model used in this study is suitable for explaining the elderly people’s intention to continue fruit and vegetable consumption. It is recommended that policy-makers use appropriate strategies to increase the understanding of the benefits of eating fruits and vegetables by the elderly and, thus, sensitize them to increase their consumption through public campaigns and communication with the relevant organizations, families, etc.
