Dietary diversity is an indicator of the access dimensions of household food security as it relates to income, area, and seasonality. Dietary diversity refers to the number of different individual food items (food variety) and food groups (food group variety) consumed over a given reference period (Ruel, 2002:3). This may accurately predict individual nutrient adequacy and thus household food security. Inability to access enough food for a sustainable and healthy life indicates food insecurity. Food accessing refers to obtaining food for all household members at all times through own production, exchange and/or purchase. Food access depends on an adequate, stable, local food supply, and includes the availability and utilization of food (Steyn, Labadarios&Huskissom, 1999: 32). Lack of food resources often leads to food insecurity due to, among other, limited dietary diversity (different foods items or food groups) (Bellamy, 1998:24). Emphasis on dietary diversity can eliminate nutrient deficiency by increasing individual food and food group variety, thereby improving health. The aim of this research is to identify and describe the contribution of food access strategies to dietary diversity of farm worker households by identifying their dietary diversity level and its contribution to household food security. A cross-sectional research design was used to collect data from all the adult women (18-65 years) (N=21) responsible for the food in a complete community of farm worker households on a farm (Oranje farm) in the Free-State province of South Africa. A structured questionnaire was used to gather data on demographics, food access strategies with special reference to food production, purchasing, bartering, gathering and payment in kind, as well as dietary diversity. The two most common food accessing strategies used were purchasing (general dealers) and gathering (wild leaves, hunting, and fishing). Most people depended on own food production (86%) such as the cultivation of vegetables (spinach, green beans, pumpkin, turnip, tomatoes, cabbage) and fruit (apricots, peaches). Food bartering is seldom practiced (19%) due to customs and lack of knowledge. Food received as payment in kind (maize meal) was common (76%). The choice method of food access was buying (76%), gathering (19%) and producing (4%). People seldom ate outside their own home (76%), except children receiving food at school from the school feeding scheme (90%). Dietary diversity was limited for cereals consisting mainly of maize meal porridge, bread, vegetables such as wild leafy vegetables, tomatoes, onions, and potatoes, fruit (apples), unpasteurised milk, protein (eggs, chicken) and other (tea, sugar, oil, curry powder). The mean for the food variety score of the 109 food items per day varied from 23.0 to 27.9 between five seasons which relates to three to four different food items per day. Food variety score were thus lower in all the seasons when considering nutritious food. The food group diversity score was also calculated over nine nutritious food groups used over seven days. The food group diversity scores was high in almost all the seasons. The mean food group diversity score of the nine food groups varied from 7.9 to 8.8 between five seasons which relates to one and almost two food groups per day. Although most food groups were consumed in seven days, resulting in “high” dietary diversity, the numbers of food items (individual food variety) eaten within the various food groups was low. This study showed that it was possible to predict household food security of household members by simply calculating the food variety score and food group diversity score of a household as an indication of dietary diversity. The result revealed which households was food secure on insecure, and provided an overall picture of the dietary diversity of the whole community. Overall this results indicated that limited food access strategies were utilized or that many of the strategies were not used optimally, resulting in limited dietary diversity, ultimately affecting the household food security status of farm worker households. This information can be used to formulate strategies and develop interventions to increase the number of food access strategies utilized and to food improve utilization thereof in order to improve dietary diversity and household security. / Dissertation (MConsSci (General))--University of Pretoria, 2008. / Consumer Science / unrestricted

Thesis (M.Sc. (Geography)) -- University of Limpopo, 2019 / South Africa’s population is more than 60% urbanised. Although food poverty has historically been associated with rural communities, this is no longer the case. With sustained urbanisation, food insecurity is now being experienced in the urban areas as well. The aim of this study was therefore to assess household food security levels and determinants, and to examine household food security coping strategies in Brazzaville informal settlement, Pretoria. The study adopted a quantitative approach which involved the collection of information through a standardised household questionnaire. A statistically representative sample of 95 households participated in the study. Household questionnaires were used to collect information on household demographics, income and expenditure statistics, poverty data as well as household food access issues. In terms of data analysis, the survey used three measures of household food insecurity: a) the Household Food Insecurity Access Prevalence Indicator (HFIAP); b) the Household Dietary Diversity Score (HDDS); and c) the Months of Adequate Household Food Provisioning (MAHFP) measurements of household food access. The survey results indicate that 29.5% of households in Brazzaville informal settlement were food secure and 70.5% food insecure. Contrary to conventional wisdom of female-headed households being the most food insecure, results of this study show that maleheaded households were the most food insecure. In addition, households with low incomes, low level of education, and high unemployment were also likely to be food insecure. The results of the regression analysis suggest that gender, household income, and employment influences household food security. The probability of food security decreases if household is headed by a female, because females can adopt multiple coping strategies. The study concludes that food insecurity coping strategies vary significantly from one household to another according to their expenses, objectives and constrains.

Increasing amounts of food waste is becoming a problem in developed countries. This research project is about how to reduce food waste by tracking fridge inventory and the best-before date of fridge stored food by a smartphone application. Food waste occurs in several different ways. It can be found in the household, retail stores and in the catering and events sector. Food waste can also be classified as avoidable waste, possibly avoidable waste and unavoidable waste. This project focuses on the household sector and the use of a mobile application to track fridge inventory and best-before date. The purpose of the application is to try to reduce household food waste. There is previous research about reducing household food waste using mobile applications and they all take different approaches. This study focuses on building upon these previous approaches together with data gathered from our own questionnaire with Sweden as primary focus. The combined data results in our own mobile application solution that has been tested by users in Swedish households. The study’s research question is addressed by the use of the application during a period of one-week observation. Our data collection consists of the participants being interviewed at the end of the observation period. The interviews gathered information related to whether the users successfully reduced food wastage in their households.

Objective: There is little evidence of how fruit and vegetable (FV) household food availability changes over a one-month period among low-income households. The objective of this study was to analyze how FV variety and sustainability changes over a 4-week period. Design: Inventories were conducted in low-income family households (n=49) once a week over a 4-week period. Trained researchers gathered the weights of all FV, including legumes, within the home. Previously determined mean container weights were subtracted to obtain the estimated weight of the FV. All weights were then converted to edible cups of FV, taking into account the weight that is removed when stems, peels, skins, and canning liquid are removed. Analysis: Variety was measured by analyzing the number of kinds of FV within the USDA subgroups (100% fruit juice, citrus fruits, other fruits, dark green vegetables, orange vegetables, dry beans and peas, starchy vegetables, and other vegetables) found in the home. In addition, sustainability was analyzed by the number of days into the future at which households can meet 100% of the FV recommendations. Data were combined for all households, according to the time points with the most amount of FV (HFV), the second-most amount of FV, the third-most amount of FV, and the least amount of FV (LFV) available in the household. Results: Vegetables, specifically canned vegetables, comprised the majority of all measurements taken throughout all inventories. When combined, the kinds of total FV decreased significantly from 25±1.1 kinds on HFV to 21.2±1.1 kinds on LFV (p<.0001). Days into the future at 100% of the fruit recommendation fell significantly from 11.4±0.1 days on HFV to 7.1±0.1 days on LFV (p<.0001). Total vegetables decreased significantly from 25.3±0.1 days on HFV to 19.1±0.1 days on LFV (p<.0001). Even at the peak of FV availability, dark green vegetables remained the lowest subgroup at 2.17±0.1 days and decreased to 1.6±0.1 days at LFV (p=0.01). Conclusions and Implications: Low-income households have greater variety of FV during the times when they have the most food resources compared to when they have the least food resources. The days into the future that the household FV supply could be maintained at 100% of the USDA's subgroup recommendation varies widely between subgroups, from about two days up to more than one month. Further research is needed to determine how to maintain subgroup variety and constancy of a FV supply throughout the month for low-income FV.

Food waste is a global concern with significant environmental, economic, and social implications. Despite efforts to address the issue, household-level food waste remains substantial, contributing to food insecurity and environmental degradation. This study aims to explore factors triggering food waste behavior within households and examines how grocery retailers can nudge consumers toward environmentally sustainable food waste practices. A qualitative research design was used, involving semi-structured interviews with 20 participants in Sweden responsible for food management. Thematic analysis of interview recordings revealed key findings. Participants' food waste awareness centered on economic concerns, with limited consideration for environmental and social impacts. Planning emerged as a crucial aspect of food waste reduction, highlighting the need for tools like shopping lists. Additionally, conscious shopping habits were associated with reduced food waste, regardless of frequency or bulk purchasing tendencies. The practical implications for retailers include raising awareness through educational campaigns, integrating waste reduction messages into marketing materials, and providing inventory management tools and personalized shopping lists. Retailers can further support sustainable food waste behavior by offering recipe suggestions and workshops on food disposal or repurposing. Implementing these strategies can contribute to more sustainable food waste practices.

Introduction: While the paradoxical association between overweight and household food insecurity (HFI) is well established amongst low-income women, findings remain inconclusive amongst children. The purpose of this study was to determine the relationship between household food insecurity (HFI) and child overweight outcomes in an inner-city, pre-school and school aged population. Methods: This study used a cross-sectional study design augmented by validated Early Pregnancy Study (EPS) data collected during a pregnancy 6 years prior. A random subset of mothers of child-bearing age (23-44 years) and the child resulting from that pregnancy (between 4-7 years of age at time of re-enrollment) were tracked and re-enrolled in this follow-up study. The primary exposure, HFI, was captured using an adaptation of the standardized US Food Security Scale -- embedded within a larger self-report questionnaire addressing selected maternal and child influences (such as health, exercise, and dietary risk factors) on child weight patterns. Maternal and the child BMI outcome was determined through in-home clinical assessment of height and weight and using standard CDC based cutoffs to classify weight status. Self-report and biologically confirmed prenatal EPS data were also obtained to establish useful baseline data and to enhance study results. Exploratory hypotheses examined: (1) Interrelatedness between select maternal and child health, social-environmental, and socio-demographic exposures and (2) Household food insecurity (HFI), prenatal and current maternal and child exposures were explored for their relationship with child BMI. Results: Thirty-six mother-child dyads participated in this follow-up study. Twenty-eight percent of mothers reported HFI; 83% of mothers were classified as overweight or obese and 58% of children were categorized as at-risk for overweight or overweight. Most bi-variate analyses yielded non-significant results, though in-utero drug use was significantly correlated, and mothers who tested positive for tobacco use during pregnancy were also likely to test positive for marijuana use, as determined through biological confirmation (p&lt;0.05). Additionally, current maternal BMI as well as current maternal hip-to-waist ratio were each significantly associated with current child BMI (p&lt;0.05). One unexpected finding included a significant association between current maternal BMI and presence of a co-morbidity in the child (p&lt;0.05). No significant relationships were found between HFI or additional exploratory multivariate models looking at independent effects of prenatal and current maternal-child exposures in predicting child overweight, though current maternal BMI was predictive of child overweight in most analyses. Access to electronic medical record information was highly predictive of participation in this follow-up study (p&lt;0.001). Discussion: This study provided an opportunity to better characterize an attrition-prone population, and, while it is possible to track and identify these women through electronic medical record databases, recruitment efforts were labor-intensive and attrition rates particularly high (~22% of mothers re-enrolled). Overall, the influence of household food insecurity on child overweight remains unclear. However, study findings also demonstrated that maternal weight alone was highly predictive of child overweight as early as pre-school, mirroring empirical evidence in this area. Ultimately, childhood obesity is more effectively prevented when treated as a familial concern. Future studies should continue to explore cumulative influences catalyzing obesity in young children in order to better inform understanding of early obesity onset. / Public Health
