To assess the association between food insecurity and depression symptom severity stratified by sex, and test for evidence of effect modification by social network characteristics.

A population-based cross-sectional study. The nine-item Household Food Insecurity Access Scale captured food insecurity. Five name generator questions elicited network ties. A sixteen-item version of the Hopkins Symptom Checklist for Depression captured depression symptom severity. Linear regression was used to estimate the association between food insecurity and depression symptom severity while adjusting for potential confounders and to test for potential network moderators.

In-home survey interviews in south-western Uganda.

All adult residents across eight rural villages; 96 % response rate (n 1669).

Severe food insecurity was associated with greater depression symptom severity (b=0·4, 95 % CI 0·3, 0·5, P<0·001 for women; b=0·3, 95 % CI 0·2, 0·4, P<0·001 for men). There was no evidence of effect modification by social network factors for women. However, for men who are highly embedded within in their village social network, and (separately) for men who have few poor contacts in their personal network, the relationship between severe food insecurity and depression symptoms was stronger than for men on the periphery of their village social network, and for men with many poor personal network contacts, respectively.

In this population-based study from rural Uganda, food insecurity was associated with mental health for both men and women. Future research is needed on networks and food insecurity-related shame in relation to depression symptoms among food-insecure men.

To investigate the association of seasonality with dietary diversity, household food security and nutritional status of pregnant women in a rural district of northern Bangladesh.

A cross-sectional study was conducted from February 2013 to February 2015. Data were collected on demographics, household food security (using the Household Food Insecurity Access Scale), dietary diversity (using the women’s dietary diversity questionnaire) and mid-upper arm circumference. Descriptive statistics were used to explore demographics, dietary diversity, household food security and nutritional status, and inferential statistics were applied to explore the role of seasonality on diversity, household food security and nutritional status.

Twelve villages of Pirganj sub-district, Rangpur District, northern Bangladesh.

Pregnant women (n 288).

Seasonality was found to be associated with dietary diversity (P=0·026) and household food security (P=0·039). Dietary diversity was significantly lower in summer (P=0·029) and spring (P=0·038). Food security deteriorated significantly in spring (P=0·006) and late autumn (P=0·009).

Seasons play a role in women’s household food security status and dietary diversity, with food security deteriorating during the lean seasons and dietary diversity deteriorating during the second ‘lesser’ lean season and the season immediately after. Interventions that aim to improve the diet of pregnant women from low-income, subsistence-farming communities need to recognise the role of seasonality on diet and food security and to incorporate initiatives to prevent seasonal declines.

To assess the validity and reliability of the Arabic version of the Household Food Insecurity Access Scale (HFIAS) in rural Lebanon.

A cross-sectional study on a sample of households with at least one child aged 0–2 years. In a one-to-one interview, participants completed an adapted Arabic version of the HFIAS. In order to evaluate the validity of the HFIAS, basic sociodemographic information, anthropometric measurements of the mother and child, and dietary intake data of the child were obtained. In order to examine reproducibility, the HFIAS was re-administered after 3 months.

Rural Lebanon.

Mother and child pairs (n 150).

Factor analysis of HFIAS items revealed two factors: ‘insufficient food quality’ and ‘insufficient food quantity’. Using Pearson's correlation, food insecurity was inversely associated with mother's and father's education levels, number of cars and electrical appliances in the household, income, weight-for-age and length-for-age of the child and the child's dietary adequacy. In contrast, mother's BMI and crowding index were positively associated with food insecurity scores (P < 0·05 for all correlations). Cronbach's α of the scale was 0·91. A moderate correlation was observed between the two administrations of the questionnaire (intra-class correlation = 0·58; P < 0·05).

Our findings indicated that the adapted Arabic version of the HFIAS is a valid and reliable tool to assess food insecurity in rural Lebanon, lending further evidence to the utility of the HFIAS in assessing food insecurity in culturally diverse populations.

To assess the validity of a locally adapted Household Food Insecurity Access Scale (HFIAS) in the measurement of household food insecurity (FI) in the city of Tehran.

A cross-sectional study.

Urban households were selected through a systematic cluster sampling method from six different districts of Tehran. The socio-economic status of households was evaluated using a questionnaire by means of interviews. An adapted HFIAS was used to measure FI. Content validity was assessed by an expert panel, and the questionnaire was then tested among ten households for clarity. Criterion validity was assessed by comparing the measure with a number of determinants and consequences of FI. Internal consistency was evaluated by Cronbach's α and exploratory factor analysis. For repeatability, the questionnaire was administered twice to twenty-five households at an interval of 20 d and Pearson's correlation coefficient was calculated.

A total of 416 households.

In all, 11·8 %, 14·4 % and 17·5 % of the households were severely, moderately and mildly food insecure, respectively. Cronbach's α was 0·855. A significant correlation was observed between the two administrations of the questionnaire (r = 0·895, P < 0·001). Factor analysis of HFIAS items revealed two factors: the first five items as factor 1 (mild-to-moderate FI) and the last four as factor 2 (severe FI). Heads of food-secure households had higher education and higher job position compared with heads of food-insecure households (P < 0·001). Income and expenditure were lower in food-insecure households compared with food-secure households.

Adapted HFIAS showed acceptable levels of internal consistency, criterion validity and reliability in assessing household FI among Tehranians.

The purpose of the present study was to test the construct validity, internal consistency and convergent validity of the Household Food Insecurity Access Scale (HFIAS) in measuring household food insecurity in rural Tanzania, and to determine socio-economic characteristics associated with household food insecurity.

Key informant interviews and a cross-sectional survey were conducted in February and March 2008.

Rural Iringa, Tanzania.

Key informant interviews were conducted with twenty-one purposively selected male and female village leaders. For the household surveys, a sample of 237 households with mothers (caregivers) and at least one child between 1 and 5 years of age were included.

Approximately 20·7 % of the households were categorized as food-secure, 8·4 % as mildly food-insecure, 22·8 % as moderately food-secure and 48·1 % as severely food-insecure. Two main factors emerged from the rotated principal component factor analysis: (i) insufficient food quality; and (ii) insufficient food intake. Both factors explained 69 % of the total variance. The full food insecurity scale and the two subscales had good internal consistency (Cronbach’s α = 0·83–0·90). Food security, as measured by HFIAS, was positively associated with maternal education, husband’s education, household wealth status, being of an agricultural rather than pastoral tribe and animal-source food consumption; it was negatively associated with maternal age and household size.

The HFIAS measurement instrument shows validity and reliability in measuring household food insecurity among poor households in rural Tanzania.
