Abstract
Purpose
This study aimed to examine the association of shift work with depression and anxiety in a large sample of formal and contractual employees of a mill steel company, Isfahan, Iran.
Design/methodology/approach
This cross-sectional study was performed in 2014 among 3,060 formal and contractual employees of a mill steel company Isfahan, Iran, randomly selected from 16,000 people. Data gathering was done by some validated Iranian version of self-administered questionnaires including, International Physical Activity – Short Form, Effort–Reward Imbalance, Hospital Anxiety and Depression Scale. Logistic regression was used as the main statistical method.
Findings
The results showed individuals in the rotating shift compared with day shift had a higher risk of depression (OR: 1.43; 95% CI: 1.12–1.84). Whereas after adjustment for various confounders, this relationship was not significant (OR: 1.19; 95% CI: 0.81–1.76). Anxiety was not associated with shift work, both in crude and adjusted models (OR: 1.08; 95% CI: 0.81–1.44) and (OR: 0.90; 95% CI: 0.67–1.19), respectively.
Research limitations/implications
Owing to the cross-sectional design of this study, cause–effect relationships could not be inferred from our findings. All the data used in the present analysis were collected by self-administered questionnaires.
Practical implications
Although our findings did not show significant association between shift work and mental health, further studies are suggested for obtaining informative data worldwide in this regard among workforce particularly among industrial employees.
Originality/value
Few studies have addressed the effects of shift work on mental health among industrial employees worldwide, and there is no study in developing countries.

Abstract
Purpose
The purpose of this study was to evaluate the association of empirically derived dietary patterns with hypertension and hyperlipidemia among a large sample of Iranian industrial employees.
Design/methodology/approach
This cross-sectional study was done under the framework of Epidemiological Survey of Chronic Diseases on Manufacturing Employees. Major dietary patterns were derived based on a validated short form of food frequency questionnaire (FFQ) using exploratory factor analysis. Self-administered validated questionnaires were used to collect data on socio-demographic and job-related variables of participants. Multivariable logistic regression was applied for association analyses.
Findings
Higher levels of Western dietary pattern increased significantly the risk of hypertension (odds ratio [OR] = 1.85, 95% CI [1.36-2.53], P trend <0.001) and hyperlipidemia (OR = 1.45, 95% CI [1.16-1.81], p = 0.001) even after controlling for confounding variables. The traditional dietary pattern was marginally associated with a significant increase in risk of hyperlipidemia ( = 1.14, 95% CI [0.92-1.41], p = 0.084) in the fully adjusted model. However, higher levels of healthy dietary pattern were significantly associated with a decreased risk of hyperlipidemia in the final model (OR 0.80, 95% CI [0.64-0.90], p = 0.025).
Originality/value
To the authors’ knowledge, an association analysis between dietary patterns and major cardiovascular disease risk in workforce population over the world is scarce and has not yet been conducted among Iranian industrial employees. This study’s findings are especially relevant for the industrial workforce population because they are at high risk of other job-related risks that increase the CVD risk.

Abstract
Purpose
There is limited knowledge about the association of food insecurity and dietary quality among the Iranian households. The purpose of this study is to determine diet quality among the Iranian households and to investigate whether dietary quality is associated with food security status in this population.
Design/methodology/approach
The 18-item household food security questionnaire was administered to 200 households from different parts of Isfahan, Iran. Households were selected by two-stage cluster randomized sampling. Households were categorized into four groups based on their score on the questionnaire; food secure (total score 0), mild food insecure (total score 1–2), moderate food insecure (total score 3–7) and severe food insecure (total score 8–18). In the second stage of the study, 25 households were selected from each food security status group to evaluate the micronutrient adequacy and assess the adherence to Alternative Healthy Eating Index 2010 (AHEI-2010).
Findings
Food-secure households had higher adherence to the AHEI-2010 than food-insecure households (p < 0.001). Food-secure households consistently achieved higher value of the nutrient adequacy ratio for most of the micronutrients than food-insecure households, with the greatest differences seen for zinc (p < 0.001) in households (father, mother and first child), vitamin D (p < 0.001), vitamin A (father: p = 0.05, mother: p = 0.04), calcium (p < 0.001) and iron (father: p = 0.02, mother: p < 0.001) in mother and father.
Originality/value
Low dietary quality was associated with food insecurity. Food-secure households had higher micronutrient adequacy ratio for most of the nutrients.
