Ethnomedical and Sociocultural Factors of Pica Substances in Rural South India

Relationship of self-reported pica and avoidant restrictive food intake disorder symptomology with dimensions of impulsivity, perceived stress among Pakistani University students

INTRODUCTION

Pica and avoidant/restrictive food intake disorder are two of the three new eating and feeding disorders introduced in the DSM-5, this inclusion has drawn attention to the immediate need for research into their prevalence, diagnostic assessment, underlying risk factors and optimal treatment. There are very few studies available that explored the predictors or causes of these eating disorders specifically in Pakistani context.

OBJECTIVES

The objectives of the current study include (a) to estimate the presence of pica and avoidant/restrictive food intake disorder symptomology among young adults in Pakistan, (b) to examine the relationship between dimensions of impulsivity, stress and presence of pica and avoidant/restrictive food intake disorder, (c) to explore the mediation role of stress.

METHODS

The sample consisted of 660 young adults with age range 18-25 years, recruited through convenient sampling. The respondents were provided with a questionnaire comprising of an informed consent, a demographic information sheet and self-report measures including PARDI-AR-Q to assess symptomology of pica and avoidant/restrictive food intake disorder, UPPS-P Impulsive Behaviour Scale to assess dimensions of impulsivity and Perceived Stress Scale to measure perceived stress.

RESULTS

The findings show that 28 participants (4.2%) reported Pica symptomology, of which eleven participants indicated that they currently consume more than one non-food item. 19 respondents (2.8%) reported avoidant/restrictive food intake disorder symptomology. 13 respondents reported varying degrees of all three symptom clusters namely sensory based food avoidance, lack of interest in food, and fear of negative consequences of eating. Additionally, each of the dimensions of impulsivity was found to be positively correlated to the presence of pica and avoidant/restrictive food intake disorder. Perceived stress was identified as a mediating factor between each of the dimensions of impulsivity and presence of pica and avoidant/restrictive food intake disorder.

CONCLUSION

Although current study focused on a particular age range, it has drawn attention to the necessity of screening and investigating other strata of Pakistani population for pica and avoidant/restrictive food intake disorder. The clinical utility of the present research resided in the identification of factors associated with pica and avoidant/restrictive food intake disorder, an information which can be used to tailor psychological interventions, modify existing ones, and inform the future research on evidence-based treatment.

Research on feeding and eating disorders in India: A narrative review

Despite growing evidence of their prevalence, research on feeding and eating disorders (FEDs) in India has been sporadic. This narrative review aimed to summarize the research on FED in India and set priorities for future research and translation of evidence. An electronic search was conducted in the MEDLINE, PsycINFO, and Google Scholar databases to identify relevant English peer-reviewed articles from April 1967 to July 2023. The extracted data from these studies included author names, publication year, research location, type of intervention (for interventional studies), nature of comparator treatments, and main outcomes or findings. We found a rising trend in the prevalence of EDs in India. Adolescent age group, female sex, higher socioeconomic status, family history of mental illness or disordered eating, and borderline personality pattern were risk factors for EDs. For feeding disorders (FDs), childhood age group, malnutrition, pregnancy, psychosis, intellectual disability (ID), and obsessive-compulsive disorder (OCD) were putative risk factors. Both physical and psychiatric comorbidities were common in FEDs. Culture appears to exert a pathoplastic effect on symptom presentation in FEDs; an illustrative example is the documented nonfat phobic variant of anorexia nervosa (AN) in India. Research on management has focused on using assessment tools, investigations to rule out medical comorbidities, psychosocial and family-based psychotherapies, nutritional rehabilitation, pharmacotherapy, and neuromodulation approaches. Whereas the publication output on FEDs in India has increased over the last decade, it remains an under-researched area, with a striking paucity of original research. Future research priorities in FEDs include conducting country-wide registry-based studies to offer real-world insights, longitudinal research to identify culturally relevant risk factors, and developing brief, culturally sensitive diagnostic instruments for FEDs in the Indian context. This will help generate locally relevant epidemiological data on FEDs and inform treatment and prevention strategies.

Pregnancy Fasting in Ramadan: Toward a Biocultural Framework

Pregnancy fasting poses a paradox: why would a woman restrict her diet during a period of increased nutritional need? This qualitative, cross-sectional study applied biological and cultural evolutionary theories of pregnancy diet to emic models of fasting with the aim of establishing a testable biocultural framework of pregnancy fasting. The research took place with Muslim women residing in Mysore, India. In-depth interviews were conducted with pregnant women who have experience and knowledge of fasting during during the holy month of Ramadan. Our findings indicate that pregnancy fasting is socially acquired via multiple modes of transmission and that women do not fast according to mainstream evolutionary theories of pregnancy diet, but perhaps to gain moral capital.

Geophagy in India: a qualitative exploratory study on motivation and perception of female consumers

BACKGROUND

Geophagy, the consumption of soil, is well documented in Africa and other continents, but is rarely investigated in Asia and even less so in India. The main aim of this exploratory qualitative study was therefore to understand the motivation for clay consumption, the social perception of the habit, the mode and quantity of consumption, as well as subjectively perceived effects of clay consumption in Himachal Pradesh, North India.

METHODS

We conducted semi-structured interviews with 27 female geophagists aged 18-80 years.

RESULTS

We could show that geophagy exists across all ages and social groups. The main type of consumed soil is yellow clay used for house wall plastering. Geophagy is usually practised because of a craving for soil despite various fears of negative health effects. It is normally done secretly and under-reported to local doctors. The most common self-reported positive effect of geophagy was the feeling of relief. Geophagy was generally considered as harmful to health and various complaints were associated with it. It is not practised because of food shortages or as a remedy. On the contrary, it is generally seen as an addiction detrimental to health.

CONCLUSIONS

Awareness of geophagy has to be ameliorated in the Indian population and specifically among health workers to improve support for affected individuals. Geophagy should be routinely included in national antenatal care guidelines.

A test of four evolutionary hypotheses of pregnancy food cravings: evidence for the social bargaining model

The onset of cravings for items not typically desired is often considered a hallmark of pregnancy. Given the ubiquity of cravings, this phenomenon remains surprisingly understudied. The current study tested four hypotheses of pregnancy food cravings: behavioural immune system, nutrient seeking, resource scarcity and social bargaining. The research took place in Tamil Nadu, South India, with pregnant women residing in rural villages (N = 94). Methods included structured interviews and anthropometric measures. Findings revealed that unripe mango and unripe tamarind were the two most frequently mentioned food cravings among this population, but were not sufficiently supported by the a priori models. Results confirmed that the social bargaining model was the best explanation for the etic category of toxic/pathogenic food items, suggesting that pregnant women crave dangerous foods when experiencing heightened social pressures. Finally, toxicity/pathogenicity was a confounding factor for the nutrient seeking and resource scarcity models, calling into question the validity of these models in adverse environments. Overall, these findings present important implications for research on pregnancy food cravings, such that in resource-scarce and pathogen-dense environments, cravings might target teratogenic items that signal a need for increased social support.
