Trends and consequences of consumption of food and non-food items (pica) by pregnant women in Western Kenya

Geophagia and risk of squamous cell esophageal cancer in the African esophageal cancer corridor: Findings from the ESCCAPE multicountry case-control studies

Geophagia, the intentional practice of consuming soil, occurs across the African esophageal cancer corridor, particularly during pregnancy. We investigated whether this practice is linked to endemic esophageal squamous cell carcinoma (ESCC) in this region. We conducted ESCC case-control studies in Tanzania, Malawi and Kenya. Cases were patients with incident histologically/clinically confirmed ESCC and controls were hospital patients/visitors without digestive diseases. Participants were asked if they had ever eaten soil (never/regularly/pregnancy-only). Odds ratios (OR) are adjusted for sex, age, tobacco, alcohol, country, religion and marital status. Overall, 934 cases (Malawi 535, Tanzania 304 and Kenya females 95) and 995 controls provided geophagia information. Among controls, ever-geophagia was common in women (Malawi 49%, Kenya 43% and Tanzania 29%) but not in men (10% Malawi, <1% Tanzania). In women, ESCC ORs were 1.25 (95% CI: 0.70, 2.22) for regular versus never geophagia and 0.88 (95% CI: 0.64, 1.22) for pregnancy-only versus never. Findings were stronger based on comparisons of cases with hospital visitor controls and were null using hospital patients as controls. In conclusion, geophagia is too rare to contribute to the male ESCC burden in Africa. In women, the practice is common but we did not find consistent evidence of a link to ESCC. The study cannot rule out selection bias masking modest effects. Physical effects of geophagia do not appear to have a large impact on overall ESCC risk. Research with improved constituent-based geophagia exposure assessment is needed.

Fish Acquisition and Consumption in the African Great Lakes Region through a Food Environment Lens: A Scoping Review

Effective actions for the fishery and aquaculture sectors to contribute toward improving nutrition rely on an understanding of the factors influencing fish intake, particularly amongst vulnerable populations. This scoping review synthesises evidence from 33 studies in the African Great Lakes Region to examine the influence of food environments on fish acquisition and consumption. We identified only two studies that explicitly applied a food environment framework and none that linked policy conditions with the contribution of fish to diets. Economic access to fish was represented in the largest number of included studies (21 studies), followed by preferences, acceptability and desirability of fish (17 studies) and availability and physical access (14 studies). Positive perceptions of taste and low cost, relative to other animal-source foods, were drivers of fish purchases in many settings; however, limited physical and economic access were frequently identified as preventing optimal intake. In lakeside communities, fish were increasingly directed toward external markets which reduced the availability and affordability of fish for local households. Few studies considered intra-household variations in fish access according to age, gender or physiological status, which represents an important knowledge gap. There is also scope for future research on seasonal influences on fish access and the design and rigorous evaluation of programmes and policies that address one or more constraints of availability, cost, convenience and preferences.

A Narrative Review of Nutritional Malpractices, Motivational Drivers, and Consequences in Pregnant Women: Evidence from Recent Literature and Program Implications in Ethiopia

Maternal nutrition is very important for the wellbeing of pregnant women, childbirth, and lactating women, which are crucial and meant for the wellbeing of a mother and newborn baby. This narrative review discusses nutritional malpractices, motivational drivers, and their consequences typically from Ethiopian pregnant women's context. Different studies (regarding less of study design and type) done among pregnant women (aged 15-49 years) by considering pregnancy-related outcomes and timing of nutritional malpractices were included mostly. Accordingly, taboos of healthy diets, craving for unhealthy foods (sweet, fat, raw, and salty/spicy foods), and nonfood items (soil, coffee residue, stone, and ash) were practiced majorly by the women. The birth difficulty, fetal head plastering, fetus discoloration, fetus burns, abortion, and abdominal cramp are the primary drivers of taboos of healthy diets. Hormonal change and social and nutrient-seeking behavior are the most prevalent drivers to the consumption of unhealthy foods. Additionally, personal interest, flavor, and color of items are important motivators to practice pica. Such pica practice hurts nutrient intake, absorption of iron/zinc, abdominal health, and diarrhea occurrence. Food taboos are high predictors of health disorders, such as intrauterine growth restriction, infection, bleeding, preeclampsia, stillbirth, early birth, low birth weight, retarded development of cognitive, and anemia. Craving and eating unhealthy foods were interconnected with chronic disease development (hypertension, diabetes, heart disease, and cancer), discomforts, preterm labor, preeclampsia, and intrauterine growth restriction in women. Additionally, it is also associated with stillbirth, low birth weight, obesity, birth defect/deficit, hypertension, cancer, diabetes, metabolic syndrome, renal disease, decreased fetal growth, behavioral change, heart failure, and poor cognitive development in the infant. Overall, these nutritional malpractices are significantly associated with many argumentative pregnancies as well as developmental consequences leading to the direction of infant and maternal mortality and morbidity. Therefore, urgent implementation of health and nutrition education programs considering food misconceptions and beliefs regarding pregnancy and use of ground-breaking ways to play down the negative and maximize potential positive dietary effects designed by the government of Ethiopia could also serve as a long-term solution to the problem.

What stops us from eating: a qualitative investigation of dietary barriers during pregnancy in Punjab, Pakistan

OBJECTIVE

Adequate dietary intake during pregnancy is vital for the health and nutritional status of both mother and fetus. The nutritional status of reproductive age women in Pakistan is poor, with 14 % being underweight (BMI < 18·5) and 42 % experiencing Fe deficiency anaemia. This may stem from beliefs, practices and other barriers influencing dietary intake. This qualitative study seeks to determine which factors impact dietary intake during pregnancy in rural Punjab.

DESIGN

In-depth interviews and focus group discussions were conducted and then analysed using thematic analysis.

SETTING

Three purposively selected rural districts (Sahiwal, Okara and Pakpatan) with the highest prevalence of maternal and child malnutrition in the province of Punjab, Pakistan.

PARTICIPANTS

Mothers with children under age two (n 29) and healthcare providers with at least 5 years of experience working in the district (n 12).

RESULTS

We identified a combination of physiological, socio-cultural and structural barriers that inhibited healthful dietary intake during pregnancy. The primary physiological barriers to optimal dietary intake and dietary practices included food aversions and food cravings. Food classification, fear of a difficult childbirth, fear of high blood pressure and household food politics were the principal socio-cultural barriers. Additionally, two structural barriers, inadequate antenatal counseling and a lack of affordable food options, were identified.

CONCLUSIONS

Our study demonstrates that complex barriers prevent pregnant women in the Punjab area from consuming adequate dietary intake and that antenatal health education programmes and structural interventions are needed to support healthful dietary practices during this critical period.

Dietary diversity and its correlates among pregnant adolescent girls in Ghana

BACKGROUND

Dietary diversity, a qualitative measure of dietary intake, which reflects the variety of foods consumed has been recommended to assuage nutritional problems related to insufficient micronutrients, and food insecurity. To better understand the underlying factors for poor birth outcomes in Ghana, we assessed factors associated with dietary diversity among rural and urban pregnant adolescents in the Ashanti Region of Ghana.

METHODS

As part of a larger longitudinal cohort of 416 pregnant adolescents, the FAO minimum dietary diversity for women index was used to determine the dietary diversity score (DDS) of the participants from a previous days' 24-hour dietary recall data. The household hunger scale (HHS) and lived poverty index (LPI) were used to determine hunger and socioeconomic status. Eating behavior and socio-demographic data were gathered using interviewer-administered questionnaires.

RESULTS

The mean age of the participants was 17.5 (±1.4) years with an MDD-W of 4.4 and 56% recording inadequate MDD score. More rural (63.6%) than urban dwellers (50.6%) had inadequate DDS (p = 0.008). Among all the multiple variables tests of associations on dietary diversity, only hunger status (p = 0.028) and both food aversion and poverty status (p = 0.003) had a significant effect on the adolescents' dietary diversity. Rural dwelling adolescents (AOR = 1.7, p = 0.035, 95% CI = 1.0-2.6) recorded higher odds for inadequate DD compared with the urban respondents. Pregnant adolescents with severe hunger had higher odds (Unadjusted OR = 1.9, p = 0.053, 95% CI 1.1-3.8) for inadequate dietary diversity compared with those with no hunger.

CONCLUSIONS

Inadequate DD is common among pregnant adolescents in this study and is associated with rural living, food insecurity, poverty, and food craving. Livelihood support for pregnant teenagers and nutrition education are recommended interventions to improve dietary quality and limit the consequences of poor dietary diversity.

Are anemia, gastrointestinal disorders, and pregnancy outcome associated with pica behavior?

OBJECTIVE

This study was conducted to determine the relationship between pica and anemia, gastrointestinal disorders, as well as pregnancy outcomes in pregnant women.

METHODOLOGY

This study was a prospective study carried out between January 2016 and June 2017 and was performed on 226 pregnant women who attended four different health care centers to receive routine prenatal care. Sampling was done considering the inclusion criteria, in two steps: cluster sampling and random sampling. Data collection was done using a researcher-made checklist. The significance level was set at p = 0.05.

RESULTS

The average age of the participants was 26.10±6.27. The prevalence of pica in pregnant women in the first, second, and third trimesters was 9.3, 8, and 2.1%, respectively. The most common pica craving among pregnant women was for ice and frozen materials (68.2%). There was a statistically significant relationship between gastrointestinal disorders and anemia with pica (p < 0.001). There was also a significant relationship between birth weights of babies born to mothers with pica and those without pica (p = 0.005).

CONCLUSION

Pica in pregnant women had a significant relationship with gastrointestinal disorders and anemia during pregnancy and pregnancy outcomes. Thus, in addition to providing healthcare services, health care professionals should consider patients' pica practices and make the necessary interventions.

Practices of pica among pregnant women in a tertiary healthcare facility in Ghana

Aim

This study assessed the practice of pica among pregnant women in the Ho Teaching Hospital.

Design

Descriptive cross-sectional.

Methods

Systematic sampling technique was used to recruit 286 pregnant women. Questionnaire was used to collect data. Data entered into Statistical Package for Social Sciences for analysis.

Result

Of the 286 pregnant women, 21.2% and 17.8% considered white clay and ice respectively as nutritious. Prevalence of pica was 47.5%, while 44.9% of pregnant women who practised pica reported they feel uncomfortable when they do not eat pica as 63.3% considered intake of pica as harmful. Among women who received education against pica practice, 49.4% have ever taken pica as 50.9% of them with education on effects of pica were currently engaged in the activity (χ2 = 1.93 p = .17).

Conclusion

Health professionals, especially midwives must intensify education on effects of pica among pregnant women.

Geophagy among a Cohort of Kenyan Women with Mixed HIV Status: A Longitudinal Analysis

Geophagy, the craving and purposive consumption of earth, is commonly reported during pregnancy. To date, most studies of geophagy have been cross-sectional and have not assessed its relationship with HIV infection. Therefore, to concurrently examine proposed etiologies of geophagy, a cohort of 371 women with mixed HIV status from Nyanza region, Kenya were recruited in late pregnancy and interviewed about pica at nine time points, through 21 months postpartum. Nutritional status (hemoglobin concentration and food insecurity), physical health (HIV infection and gastrointestinal distress), and psychosocial health (depression and perceived stress) were also repeatedly assessed. Prevalence of geophagy was greatest during pregnancy and decreased significantly postpartum. In a two-level hierarchical linear model, a one-unit increase in average hemoglobin (g/dL) was associated with a 35% decrease in the odds of geophagy. The adjusted odds ratios (CI) of geophagy were 3.98 (2.99, 5.29), 2.54 (1.13, 5.69), and 1.68 (1.15, 2.44) times higher if a woman was pregnant, reported diarrhea in the prior 24 hours, or was HIV positive, respectively. The adjusted odds ratio of geophagy was 1.61 (1.06, 2.45) times higher if a woman reported geophagy during childhood. Our results lend greatest plausibility to the protection hypothesis (i.e., that geophagy occurs in response to compromised immunity and/or infection). Given the high prevalence of geophagy, clinicians should regularly screen for the behavior and measure inflammatory biomarkers before treating geophagy with iron supplements, which can exacerbate some infections.

Geophagic earths consumed by women in western Kenya contain dangerous levels of lead, arsenic, and iron

OBJECTIVES

Geophagy is commonly reported by pregnant women and children, yet its causes and consequences remain poorly understood. Therefore, we sought to determine if geophagy could contribute micronutrients and/or be a source of heavy metal exposure by examining the elemental composition of earths consumed in Kakamega, Kenya.

METHODS

Ten samples of earths commonly consumed during pregnancy were collected by study enumerators and analyzed using inductively coupled plasma-atomic emission spectroscopy. Samples were either collected at markets or from walls of participants' homes, based on where participants reported most commonly sourcing their consumed earths.

RESULTS

Based on estimated intakes (40 g/day), all samples had lead levels that exceeded the provisional maximum tolerable daily intake, and one sample exceeded the threshold for arsenic. Further, estimated intakes of iron for all samples were at least 8.9 times higher than the established threshold. Elemental concentrations were also compared by the site of sample collection (market vs. household wall); market samples had significantly higher iron concentrations and lower calcium concentrations than wall samples.

CONCLUSIONS

Geophagic earths in Kakamega may be harmful because of dangerously high levels of lead, arsenic, and iron. The prevalence of geophagy among vulnerable populations underscores the importance of understanding its causes and consequences for accurate public health messaging.

Role of food taboos in energy, macro and micronutrient intake of pregnant women in western Kenya

Purpose

The purpose of this paper is to examine food taboos/habits and dietary patterns of pregnant women in Kenya.

Design/methodology/approach

In all, 205 individual 24-h recall interviews were conducted face to face to collect information on pregnant women dietary intake. Women focus group discussions were conducted in seven villages in Kakamega County to determine which foods are avoided during pregnancy and the reasons for avoiding them.

Findings

The concept of “baby becoming big” was common advice to pregnant women to reduce intake of large amounts of starchy or high caloric foods. Restriction on the consumption of some parts of cow and chicken and consumption of eggs was widespread. Women with the highest education had significantly higher intake than women with lower education: energy (1,718 vs 1,436 kcal, p = 0.007), protein (45 vs 38 g, p = 0.03), vitamin C (59 vs 39 mg, p = 0.000), calcium (275 vs 222 mg, p = 0.04) and iron (8.5 vs 7.2 mg, p = 0.03). Multivariate binary logistic regression showed that participants with higher education were more likely to reach estimated average intake for energy (OR = 2.82, 95 per cent CI = 1.2-6.5) and vitamin C (OR = 4.1, 95 per cent CI = 1.5-11.0) than women with lower education level.

Originality/value

The observed link between reduced intake of nutrients and low education levels suggests that education is a possible intervention strategy. Incorporating nutrition education in school curriculum and improving knowledge on nutrition among women with low education may help overcome unhealthy food taboos in pregnant women.
