Fishing and fish consumption contributing to the nutrient profile, dietary diversity and food security of adult caregivers in a coastal community in Rivers State, southern Nigeria

Abstract

Introduction: The contribution of fishing practices and fish consumption to food and nutrition security cannot be over emphasized, particularly where large numbers of people are poor. Nutrition research has identified fish and fishery products as key components of human nutrition as well as one of the essential foods to incorporate into daily dietary food consumption based on its potential health benefits. These benefits have promoted the consumption of fish in recent times. Fish contains proteins, vitamins and fats (Omega 3 Polyunsaturated Fatty Acids) (PUFAs) among other nutrients (Domingo 2016: 979). Recently, there has been a notable increase in the harvesting of wild stocks of fish and shellfish. Oceans are currently at their maximum sustainable yields to cope with the world’s growing population and the demand for fish and shellfish. Overexploitation and the use of harmful chemicals used in harvesting fish and oil exploitation are some of the core reasons for the global decline of fish. These factors pose a threat to the ecological health of marine resources (Bennette and Dearden 2014: 107) and the economy of low-income countries whose livelihood largely depends on fishing for household and national food security sources (Sowman and Cardoso 2010: 1164). In the research community of Buguma, the decline of the fish population is attributed to the corrosion of pipelines, sabotage and mishandling of oil production operations. The petroleum and gas/oil products from this mismanagement find access directly into the rivers and creeks. The residue from these substances settles on the ocean floor, endangering the ecosystem by killing marine life such as fish and seafood. To this end, food and nutrition insecurity have become evident in the community as livelihoods are dependent on fishing and fish is a primary source of protein. Food insecurity is further aggravated by the high rate of unemployment and low educational attainment. The households are left to apply certain strategies to cope with household food shortfalls. Having to employ certain strategies to cope with food insecurity, negatively affects nutrient adequacy. Thus, inadequate nutrient intake and imbalances have resulted in poor health outcomes and malnutrition. Aim: The study aim was to determine the fishing practices and fish consumption contributing to the nutrient profile, dietary diversity and food security of adult caregivers in a coastal community. Methodology: Two hundred and forty-seven respondents were selected using a multi-stage sampling method. The sample size was calculated using a power calculation indicating that

250 respondents represents a reliable sample out of which 247 respondents completed the research instruments. Sampling procedures were multistage (cluster and random) sampling. The study was descriptive and quantitative in nature. Research tools used to collect data were a sociodemographic questionnaire, a fishing practices questionnaire, a coping strategies questionnaire, a food frequency questionnaire, 3x24-hour dietary recall questionnaires and an anthropometric measurement questionnaire. Food frequency and food security coping strategies questionnaires were compiled through focus group discussions to establish the relevant foods consumed and the respondents were interviewed for the socio-demographic, food frequency, food security coping strategies and fishing practices data. All the respondents were also weighed and measured in order to determine Body Mass Index (BMI), Waist Circumference (WC), Waist to Height Ratio (WHtR) and Blood Pressure (BP) classified in terms of World Health Organization (WHO) reference cut-off points. Socio-demographics, fishing practices, coping strategies and food frequency data were captured on Excel spread sheets and analyzed for descriptive statistics using the Statistical Package for Social Science (SPSS) version 24.0. Data from the 24-hour recall was captured and analyzed for nutrient analysis using the MRC Food Finder® version 3.0 software and comparisons were made to the recommended nutrient standards by the World Health Organization. Results: The mean age group was 31-50 years old. Sixty-one-point one percent (n=151) of the respondents were females and males made up 38.9% (n=96). Most of the fish caught by the respondents was used for consumption (64.0%; n=126) and the rest was used for income generation (36.0%; n=71). The community had on average a secondary school education (55.5%; n=137) and recorded high rates of unemployment (80.2%; n=198) with 62.3% (n=76) actively looking for employment. The respondents indicated that between one person (47.8%; n=118) and two people (46.2%; n=114) contributed to household income. Thirty-three-point two percent (n=82) had an average income of #21,000 to #30,000 (Rand value: R3100-R4000), while 25.5% had a monthly income of #31,000 to #40,000 (Rand value: R4100-R5000), accommodating six persons (42.1%; n=104) and four persons (22.3%; n=55) in the household. Thirty-seven-point seven percent (n=93) and 25.5% (n=63) respectively complained that the household “sometimes” and “always” had insufficient funds to buy food. This had led households to adopt certain coping strategies to combat food shortages. The most frequently used strategies per mean were: “relying on less expensive or preferred foods” (11.47 ±7.949), “limiting portion size” (9.73 ±2.593) and “restricting consumption by adults in order for children to eat” (8.70 ±6.628). The negative effect of applying these coping strategies adversely compromised nutrient adequacy. The 20 top consumed foods showed consumption of more

energy dense foods and less fruits and vegetables. The Food Variety Score (FVS) indicated that 51 different individual food items with mean ±SD of 20.83. (±6.546) from all food groups were consumed. Vitamin K, Biotin, pantothenate, calcium, riboflavin and thiamine were below DRIs recommendation cutting across all age groups and genders. Inappropriate imbalances in food intake reflected in BMI, WC and WHtR. The mean BMI for men (25.07kg/m2) and women (27.66kg/m2) fells into the overweight category with a mean average of 26.36kg/m2 for both genders and age groups while only women (95.46cm) were majorly found to be at risk for an elevated WC/ central obesity per mean average. The WHtR at risk factor affected the female gender (88.70%; n=133, 19-50 years and 88.90%; n=18, 51+ years old) compared to their male (44.4%; n=78, 19-50 years and 61.1%; n=18, 51+years) counterparts. Mean high BP for systolic (146.9mmHg) and diastolic (92.2mmHg) BP occurred in women 51+ years old. Conclusion: This research revealed inappropriate eating patterns and increased risk of developing NCDs. The 20 top foods consumed showed consumption of mostly macronutrients and limited consumption of fruits and vegetables across both genders and all age groups. Overweight, at risk for WC and WHtR and High Blood Pressure (HBP) were an indication of the presence of NCDs. Food insecurity resulting from a jeopardized fishing livelihood, high levels of unemployment and low educational attainment were the main causes of a compromised nutritional status in the research community. The introduction of nutrition education and an alternative means of livelihood will assist in addressing the current food and nutrition insecurity.
