Abstract

Purpose

Despite the well-known positive effects of fruits and vegetables, their consumption in many countries is lower than those recommended. This study aims to systematically examine the effects of community-based interventions on fruits and vegetables consumption in adults.

Design/methodology/approach

To collect relevant publications, the authors searched electronic databases including PubMed/MEDLINE, Scopus and Web of Science from January 2000 to July 2021. Considering random models, this study analyzed the data using weighted mean differences (WMD) and 95% confidence intervals (CI).

Findings

Among 1,621 retrieved publications, 21 articles met the inclusion criteria. The overall effect size demonstrated that, at the end of the trials, the educational interventions increased the consumption of aggregated fruits and vegetables (WMD: 0.55 serving/day, 95%CI: 0.34, 0.77), and vegetables (WMD: 0.15, 95%CI: 0.09, 0.21, I2: 33.2%; p = 0.103) in the intervention groups, compared to the control groups.

Practical implications

The subgroup analyses that were based on the type of interventions (face-to-face education compared to online interventions), location (home-based compared to the other types of interventions) and duration (24 weeks and higher) of interventions, and accompanied financial support reduced between-group heterogeneity. An efficient interventional program on increasing fruits and vegetables consumption should be part of a multi-component project.

Originality/value

To the best of the authors’ knowledge, no systematic review and meta-analysis has provided a summary of the effects of community-based interventions on fruits and vegetables consumption in adult populations, and there is no fixed conclusion that could be drawn in this regard.

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.

Abstract

Purpose

The purpose of this study is to introduce a unified framework which integrates knowledge management processes (knowledge creation, sharing, storage and documentation and acquisition), innovation capability (product, process, marketing and organizational and organizational performance (operational, financial and product quality). Then empirically test the effect of knowledge management processes (KMP) on innovation capability (IC), the effect of IC on organizational performance (OP) and the impact of KMP on OP through the mediator (IC).

Design/methodology/approach

A questionnaire was designed and addressed to the general managers of the Jordanian companies making up the target population. Statistical techniques employed included confirmatory factor analysis and structural equation modeling (SEM) using AMOS 24 to test the hypotheses.

Findings

The results show that KMP influences IC, IC affects OP and KMP impacts OP through the mediator (IC).

Research limitations/implications

The use of longitudinal data and comparisons with this study would provide further insights that would assist in generalizing knowledge related to the relationships among KMP, IC and Os' P.

Practical implications

If organizations fully comprehend KMP and IC, they would be able to implement them successfully, creating value for their companies and improving OP.

Originality/value

The existing research on KMP and IC is primarily conceptual and descriptive in nature, and empirical research confirming the real impact of KMP when developing IC is lacking. Also. the relationship between innovation capabilities and OP has not been adequately studied. Hence, this study introduces a conceptual framework which integrates KMP, IC and OP and simultaneously empirically tests the relationships among them.
