Comparing and Contrasting Three Cultural Food Customs from Nigeria and Analyzing the Nutrient Content of Diets from These Cultures with the Aim of Proffering Nutritional Intervention

Validity and Reproducibility of a Semiquantitative Food Frequency Questionnaire and Food Picture Book in Nigeria

Background

Increasing noncommunicable diseases in Nigeria are partly related to dietary factors. However, the lack of validated nutrition assessment tools hinders the conduct of nutritional epidemiology research in this population.

Objectives

To develop a Food Frequency Questionnaire (FFQ) and Food Picture Book (FPB) for Nigerian adults, and to assess its reproducibility and validity compared with 24-h dietary recalls (24DRs) during different seasons in the year.

Methods

We compiled 202 foods for the FFQ through focus groups and consultations with local dietitians. We created an FPB with standardized food portion images to enhance the accuracy of reports of dietary intakes. We administered the FFQs to 205 purposively selected adults in Ibadan, Nigeria at ∼6 monthly intervals between November 2018 and October 2020. We evaluated the FFQ's reproducibility and validity compared with 24DR across the dry and rainy seasons by examining the consumption of common food and mixed dishes. We computed the Spearman's correlation coefficients (SCC), intraclass correlation coefficients (ICC), and Wilcoxon signed-rank tests, and generated Bland and Altman plots.

Results

Overall, we studied 110 women (53.7%) and 95 men (46.3%) with a mean age of 45.0 ± 13.4 y (mean ± SD). The reproducibility tests showed a mean ± SD SCC of 0.39 ± 0.14 and mean ± SD ICC of 0.32 ± 0.12. Higher mean ± SD SCC values were noted for cereal products (0.43 ± 0.09), starchy roots and tubers (0.45 ± 0.17), and soups (0.44 ± 0.20). Conversely, lower mean ± SD SCC values were observed for milk products (0.29 ± 0.02), solid fats (0.29 ± 0.26), and fish (0.22 ± 0.19). Regarding validity tests, the overall mean ± SD SCC was 0.27 ± 0.16 and mean ± SD ICC was 0.26 ± 0.16. We observed seasonal variations in intakes of fruits, cassava flour-based products, and nuts, although most foods did not show significant differences in intakes between seasons.

Conclusions

Our FFQ and FPB demonstrated moderate correlations and seasonal variations in intakes of certain foods, emphasizing the need to account for seasonality in dietary intakes in nutritional studies in Nigeria and similar countries.

Slim north, fat south: explaining regional differences in abnormal weights in Nigeria

Weight abnormalities (underweight, overweight, and obesity) can cause life-threatening ailments. This study investigates disparities in the prevalence of underweight, overweight, and obesity between northern and southern Nigeria and their associated factors. Using the 2018 Nigeria Demographic and Health Survey (NDHS), the study analysed a sample of 12,333 women with complete records of body mass index. The study found that southern women had lower odds of being underweight than women in the north, but the reverse was the case for overweight and obesity. The prevalence of underweight was 11.6%, and it varies from 6.9% in the southern state of Enugu to 31.6% in the northern state of Jigawa. The national prevalence of overweight was 17.9%, ranging from 6.7% in Jigawa State of the northern region to 39.9% in Lagos State of the south. Similarly, the prevalence of obesity in the north was 6.1% compared to 14.4% in the south, with Anambra State of the southern region recording the highest figure of 35.5% compared to 2.1% in the Yobe State of the northern region. In all, the rate of abnormal weight was significantly higher in the south than in the north. However, the type of weight abnormality varies between the two regions. Religion, education, use of contraceptives, and wealth were associated with the three forms of abnormal weights. However, while religion was significantly associated with obesity in the north, the association was not significant in the south. This study found that wealth and education have dissimilar influences on overnutrition. While the odds of being overweight and obese increase with wealth, being educated up to a secondary level significantly reduces the odds in Nigeria and across the two regions.

Diabetes Mellitus as a risk factor for stroke among Nigerians: A systematic review and meta-analysis

Background

Diabetes mellitus is one of the modifiable risk factors for stroke. Stroke is common in Nigeria, but there is a paucity of national data on the frequency of diabetes in stroke. This study aimed to estimate to what extent diabetes a risk factor for stroke in Nigeria.

Methods

The study design is a systematic review, and the PRISMA guidelines were strictly followed. African Journal Online (AJOL), PubMed, SCOPUS and Google Scholar were systematically searched. The Newcastle-Ottawa scale was used to assess the quality, heterogeneity was determined with the I² statistic, and the DerSimonian Laird random effect model was selected for the meta-analysis.

Results

The studies were distributed across different regions of the country. The total sample size was 9397. The weighted average age of the patients with stroke was 53.7 years. The attributable risk of diabetes in stroke, among Nigerian patients, was 0.20 (95% CI: 0.17-0.22; p < 0.0001). The attributable risk has been rising steadily since the advent of the new century, and it is relatively higher in southern Nigeria.

Conclusion

The attributable risk of diabetes in stroke, among Nigerian patients is high. This varies across the regions but it is rising progressively nationally.

Fathers' Complementary Feeding Support Strengthens the Association Between Mothers' Decision-Making Autonomy and Optimal Complementary Feeding in Nigeria

Background

Evidence about the effects of mothers' decision-making autonomy on complementary feeding is not consistent, generating hypotheses about whether complementary feeding social support moderates the relation between mothers' decision-making autonomy and the practice of complementary feeding.

Objectives

This study examined the moderation effect of fathers' complementary feeding support on the association of mothers' decision-making autonomy with the WHO complementary feeding indicators of minimum dietary diversity, minimum meal frequency, and minimum acceptable diet, and post hoc secondary outcomes of feeding eggs or fish the previous day. The study also examined the concordance between mothers' and fathers' perspectives of mothers' autonomy and fathers' complementary feeding support.

Methods

Data were from cross-sectional surveys of 495 cohabiting parents of children aged 6-23 mo enrolled in an Alive & Thrive initiative implementation research study in Kaduna State, Nigeria. Logistic regression models were used to examine moderation, and κ statistics and 95% CIs were used to assess the concordance in reported perspectives of the parents.

Results

The moderation results show that the simple slopes for decision-making were significant for minimum meal frequency, minimum acceptable diet, and feeding children fish the previous day when fathers offered ≥2 complementary feeding support actions. There were no significant findings in the moderation models for minimum dietary diversity or feeding children eggs the previous day. The findings from the concordance tests show moderate to substantial agreement (ranging from 57.6% to 76.0%) between parents' perspectives of mothers' autonomy, and moderate to excellent agreement (ranging from 52.1% to 89.1%) between parents' perspectives of fathers' complementary feeding support.

Conclusions

In Nigeria, high levels of fathers' complementary feeding support strengthen the association of mothers' decision-making autonomy with minimum meal frequency, minimum acceptable diet, and feeding children fish the previous day.This study was registered with clinicaltrials.gov (NCT04835662).

Maternal and paternal involvement in complementary feeding in Kaduna State, Nigeria: The continuum of gender roles in urban and rural settings

Household gender roles influence infant and young child feeding behaviours and may contribute to suboptimal complementary feeding practices through inequitable household decision‐making, intra‐household food allocation and limited paternal support for resources and caregiving. In Igabi local government area of Kaduna State, Nigeria, the Alive & Thrive (A&T) initiative implemented an intervention to improve complementary feeding practices through father engagement. This study describes household gender roles among A&T participants and how they influence maternal and paternal involvement in complementary feeding. We conducted 16 focus group discussions with mothers and fathers of children aged 6–23 months in urban and rural administrative wards and analysed them using qualitative thematic analysis methods. Most mothers and fathers have traditional roles with fathers as ‘providers’ and ‘supervisors’ and mothers as ‘caregivers’. Traditional normative roles of fathers limit their involvement in ‘hands‐on’ activities, which support feeding and caring for children. Less traditional normative roles, whereby some mothers contributed to the provision of resources and some fathers contributed to caregiving, were also described by some participants and were more salient in the urban wards. In the rural wards, more fathers expressed resistance to fathers playing less traditional roles. Fathers who participated in caregiving tasks reported respect from their children, strong family relationships and had healthy home environments. Our research findings point to the need for more context‐specific approaches that address prevalent gender normative roles in complementary feeding in a variety of settings.

•

Some mothers and fathers still hold traditional attitudes about their roles in feeding and caring for children.

•

Traditional gender normative roles of fathers limit their involvement in the ‘hands‐on’ activities that support feeding and caring for children.

•

Some mothers and fathers are performing ‘non‐traditional’ gender normative roles despite social disapproval.

•

The shifts from the traditional roles of mothers and fathers are more salient in urban compared with rural wards.

Statin-use and perceptions of high cholesterol as predictors of healthy lifestyle behaviours in Nigerians

It is unclear how statin-use influences the adoption of healthy lifestyle choices. It is important to understand the nature of this relationship as this could facilitate targeted public health interventions which could help promote a healthy lifestyle, curb the rise of non-communicable diseases, and facilitate overall health. This study aimed to explore whether statin-use influenced the adoption of healthy lifestyle choices by changing the way urban and semi-urban Nigerians thought about their high cholesterol and their future risk of cardiovascular disease. Structured questionnaires were used to compare the lifestyle behaviours, perceptions of high cholesterol and future risk of cardiovascular disease of statin users and non-statin users recruited in urban and a semi-urban Nigeria. In-depth, face-to-face interviews were used to further explore the relationship between statin-use and the adoption of healthy lifestyle choices, and explore the influence of personal and social factors on this relationship. The odds of adopting a low-fat diet increased as perceived statin-effectiveness increased (OR = 2.33, p<0.05), demonstrating a synergistic relationship between statin-use and the adoption of healthy of lifestyle choices. In addition to this synergistic association, at interview, two other relationships were found between statin use and the adoption of healthy lifestyle choices: an antagonistic relationship fuelled by a strong perception of statin effectiveness and a perceived inability to make healthy lifestyle changes, which favoured statin-use, and an antagonistic relationship fuelled by congruous cause-control beliefs and concerns about medication-use which favoured the adoption of healthy lifestyle choices. The odds of adopting a low-fat diet was 5 times greater in urban dwellers than in semi-urban dwellers (p<0.01). Statin-use influenced the adoption of healthy lifestyle choices in three different ways, which require exploration at clinical consultation. Gender, social obligations, and physical environment also influenced statin-use and the adoption of healthy lifestyle choices.

Protein intake adequacy among Nigerian infants, children, adolescents and women and protein quality of commonly consumed foods

Protein is important for growth, maintenance and protection of the body. Both adequacy of protein quantity and protein quality in the diet are important to guarantee obtaining all the essential amino acids. Protein-energy malnutrition is widely present in developing countries such as Nigeria and might result in stunting and wasting. Needs for protein differ depending on age and physiological status and are higher during growth, pregnancy and lactation. The present review assessed protein quantity and quality in diets of Nigerian infants, children, adolescents, and pregnant and lactating women. Literature reviews and calculations were performed to assess adequacy of Nigerian protein intake and to examine the Nigerian diet. The digestible indispensable amino acid score was used to calculate protein quality of nine Nigerian staple foods and of a mixture of foods. The Nigerian population had mostly adequate protein intake when compared with the most recent protein recommendations by the FAO (2013) and WHO/FAO/UNU (2007). An important exception was the protein intake of adolescent girls and pregnant and lactating women. Most of the assessed Nigerian plant-based staple foods were of low protein quality and predominantly lacked the amino acid lysine. The addition of animal-source foods can bridge the protein quality gap created by predominance of plant-based foods in the Nigerian diet. The methodology of this review can be applied to other low- and middle-income countries where diets are often plant-based and lack variety, which might influence protein intake adequacy.
