Nutrition transition in South Asia: the emergence of non-communicable chronic diseases

Media use and excess body weight among women in Nigeria: a cross-sectional study

OBJECTIVES

To investigate the (1) time trends in body mass index (BMI) and (2) relationship between media use and body weight status among adult women in Nigeria. We hypothesise that higher frequency of media use is associated with higher likelihood of being overweight and obesity among adult women.

STUDY DESIGN

Cross-sectional.

SETTING

Urban and rural settings in Nigeria.

PARTICIPANTS

Adult non-pregnant women aged between 15 and 49 years.

METHODS

Data were derived from Nigeria Demographic and Health Surveys conducted in 2003, 2008 and 2013. The outcome variable was excess body weight (overweight and obesity), and main explanatory variables were frequency of reading newspaper, listening to radio and television (TV) viewing. Datasets were merged to perform pooled analysis, and were analysed using bivariate and multivariable regression techniques.

RESULTS

Of the 69 401 participants, 16.2% had a BMI of 25.0-29.9 kg/m² (95% CI 15.8 to 16.6) and 6.6% had >30 kg/m² (95% CI 6.3 to 6.9). Between 2003 and 2013, the prevalence of overweight women increased by 4.1%, and that of obesity by 2.2%. Overall, radio was the most popular media followed by TV and newspaper. Respectively, 15.6% and 11.7% of the women reported using radio and TV almost every day and 30.6% and 25.1% at least once a week. In multivariable analysis, watching TV almost every day and at least once a week were associated with, respectively, 1.6 and 1.2 times higher odds of being overweight, and 2.7 and 1.5 times higher odds of being obese compared with those who never used radio. Similarly, significant associations were observed for newspaper and radio use as well.

CONCLUSION

The prevalence of overweight and obesity is noticeably high among Nigerian women and has been increasing steadily over the past decade. A statistically significant association exists between BMI and the use of newspaper, radio and TV. Further studies are required to develop a better understanding of the mechanisms that underlie this relationship.

Fruit and vegetable consumption and anemia among adult non-pregnant women: Ghana Demographic and Health Survey

BACKGROUND

Anemia is the most widely prevalent form of micronutrient deficiency that affects over a quarter of the global population. Evidence suggests that the burden of anemia is higher in the developing countries with women of reproductive age and children being the most at-risk groups. The most common causes are believed to be malnutrition and low bioavailability of micronutrients, which usually result from poor dietary habits and inadequate intake of food rich in micronutrients such as fresh fruits and vegetables. Regular consumption of F&V was shown to have protective effect against NCDs; however, evidence on this protective effect against micronutrient deficiency diseases are limited.

OBJECTIVES

(1) To measure the prevalence of anemia among adult non-pregnant women in Ghana, and (2) to investigate if there is any cross-sectional relationship between F&V consumption and anemia.

METHODS

This is a cross-sectional study based on data extracted from the Ghana Demographic and Health Survey, 2008. Subjects were 4,290 non-pregnant women aged between 15 and 49 years. Hemoglobin levels were measured by HemoCue® hemoglobin-meter. Association between anemia and F&V consumption was assessed by multivariable regression methods.

RESULTS

Findings indicate that well over half (57.9%) of the women were suffering from anemia of some level. The percentage of women consuming at least five servings of fruits and vegetables a day were 5.4% and 2.5% respectively. Results of multivariable analysis indicated that among urban women, consumption of <5 servings fruits/day was associated with significantly higher odds of severe [AOR = 9.27; 95% CI [5.15-16.70]] and moderate anemia [AOR = 6.63; 95% CI [4.21-10.44]], and consumption of <5 servings of vegetables/day was associated with higher odds of moderate anemia [AOR = 2.39; 95% CI [1.14-5.02]] compared with those who consumed >5 servings/day.

CONCLUSION

The findings indicate that urban women who did not maintain WHO recommended level of F&V consumption bear a significantly higher likelihood of being moderate to severely anemic.

The importance of Evolutionary Medicine in developing countries: A case for Pakistan's medical schools

Evolutionary Medicine (EM) is a fundamental science exploring why our bodies are plagued with disease and hindered by limitations. EM views the body as an assortment of benefits, mistakes, and compromises molded over millennia. It highlights the role of evolution in numerous diseases encountered in community and family medicine clinics of developing countries. It enables us to ask informed questions and develop novel responses to global health problems. An understanding of the field is thus crucial for budding doctors, but its study is currently limited to a handful of medical schools in high-income countries. For the developing world, Pakistan's medical schools may be excellent starting posts as the country is beset with communicable and non-communicable diseases that are shaped by evolution. Remarkably, Pakistani medical students are open to studying and incorporating EM into their training. Understanding the principles of EM could empower them to tackle growing health problems in the country. Additionally, some difficulties that western medical schools face in integrating EM into their curriculum may not be a hindrance in Pakistan. We propose solutions for the remaining challenges, including obstinate religious sentiments. Herein, we make the case that incorporating EM is particularly important in developing countries such as Pakistan and that it is achievable in its medical student body.

Household food insecurity is independently associated with poor utilization of maternal healthcare services in Bangladesh

Introduction: Food insecurity at the individual level has been shown to be associated with the adoption of risky behavior and poor healthcare-seeking behavior. However, the impact of household food insecurity (HFI) on the utilization of maternal healthcare services (MHS) remains unexplored. In this study, we aimed to investigate whether or not household food insecurity was associated with non/inadequate utilization of MHS.

Methods: Participants consisted of 3562 mothers aged between 15 and 49 years and with at least one child. The outcome variable was the utilization of MHS, e.g., institutional delivery, attendance ante-, and pre-natal visits. The explanatory variables included various sociodemographic factors (e.g., age, residence, education, wealth) apart from HFI. HFI was measured using the Household Food Insecurity Access Scale (HFIAS).

Result: The prevalence of non- and under-utilization of MHS was 5.3 and 36.5, respectively. In the multivariate analysis, HFI, wealth index, and educational level were independently associated with MHS status. The odds of non- and under-utilization of MHS were 3.467 (CI = 1.058–11.354) and 4.104 (CI = 1.794–9.388) times higher, respectively, among women from households reporting severe food insecurity.

Conclusion: Severe HFI was significantly associated with both under- and non-utilization of MHS. Interventions programs that address HFI and the empowerment of women can potentially contribute to an increased utilization of MHS.

Household wealth status and overweight and obesity among adult women in Bangladesh and Nepal

BACKGROUND

In South Asia, women were reported to be more likely to have higher normal body weight. However, nationally representative evidence on the association between socioeconomic status and body weight in terms of regional cut-offs for body mass index is limited for South Asian women. This study aimed to address this gap by investigating the association between household wealth status and overweight and obesity among adult women in Bangladesh and Nepal.

METHODOLOGY

Cross-sectional data on 6,144 Nepalese and 17,683 Bangladeshi women were obtained from most recent Demographic and Health Surveys in these countries. Cut-offs for overweight and obesity were defined as per World Health Organization recommendation for South Asian population.

RESULTS

The mean age of respondents was respectively 28.76 (9.74) and 31.01 (9.21) in Nepal and Bangladesh. The prevalence of obesity and overweight was respectively 13.5% and 14% for Nepal and 15.3% and 24.2% for Bangladesh. Compared with women living in poorest households, the odds of being overweight were respectively 3.44, 2.12, 1.46 and 1.19 times higher for women living in richest, richer, middle and poorer wealth status households in Nepal. In Bangladesh, compared with poorest households, women in richest, richer, middle and poorer households had respectively 98%, 60%, 32% and 22% higher odds of being overweight. Among Bangladeshi women, the odds of being obese in richest households were 4.62 (adjusted odds ratio = 4.572; 95% confidence interval = 3.813-5.484) times and among Nepalese women 8.54 (adjusted odds ratio = 8.452; 95% confidence interval = 5.228-13.663) times higher compared with those in poorest households.

CONCLUSION

Higher household wealth is associated with an increased likelihood of being overweight and obese among adult women in Bangladesh and Nepal. Using the regional cut-offs for body mass index shows that the prevalence of obesity among women has for the first time exceeded that of overweight in both countries.

Temporal Trends in Dietary Macronutrient Intakes among Adults in Rural China from 1991 to 2011: Findings from the CHNS

Few studies have examined nutrition transitions among the rural population of China, even though half of the Chinese population (about 700 million) is living in rural China. To fill this research gap, we examined temporal trends in dietary macronutrient intakes in members of the Chinese rural population aged 18-60 years. The analysis used data from consecutive three-day dietary recalls, collected from the China Health and Nutrition Surveys (CHNS). Mixed-effect models were constructed to obtain adjusted means and to examine temporal trends after adjusting for intra-class correlation within clusters and covariates, including age, sex, geographical region, urbanicity, and income. From 1991 to 2011, a downward trend in daily energy, protein, and carbohydrate intakes was seen in all categories, with a significant reduction among all rural people (p < 0.0001). In contrast, a significant increment in daily fat intake, the proportion of energy from fat, and the proportion of rural people consuming a diet with more than 30% of energy from fat, were observed in the present study (p < 0.0001). These results suggest that adults in rural China have been undergoing a rapid nutrition transition towards a high-fat diet. Therefore, more emphasis should be placed on the quality of fat and maintaining a balanced diet during the process of nutritional education.

Frequency of TV viewing and prevalence of overweight and obesity among adult women in Bangladesh: a cross-sectional study

BACKGROUND

Research in developed countries has demonstrated an association of varying degrees between watching TV and the risk of being overweight and obese. However, there is no evidence of such an association in the context of the South Asian population.

OBJECTIVE

To investigate whether watching TV increases the risk of being overweight and obese among women in Bangladesh.

SETTING

Rural and urban areas in Bangladesh.

PARTICIPANTS

Participants were 16 624 non-pregnant women aged between 15 and 49 years.

METHODS

The study was based on cross-sectional data from the Bangladesh Demographic and Health Survey (BDHS) conducted in 2014. The main outcome variables were overweight and obesity measured by body mass index. Data were analysed by using descriptive statistics, cross-tabulation and multivariable logistic regression models.

RESULTS

The prevalence of overweight and obesity in the sample population were, respectively, 4.5% (4.18% to 4.82%) and 20% (95% CI 19.39% to 20.61%). In the multivariable analysis, no statistically significant association was found between watching TV and being overweight. However, the odds of being obese among rural women were 63% higher (adjusted OR (AOR) 1.625, 95% CI 1.179 to 2.241) among those who watched less than once a week, and 68% (AOR 1.683, 95% CI 1.029 to 2.751) higher among women who watched TV at least once a week compared to those who did not watch TV at all. Urban women who watched TV at least once a week were 67% more likely to be obese (AOR 1.665, 95% CI 1.079 to 2.568) compared to those who did not watch at all.

CONCLUSIONS

Prevalence of overweight and obesity has risen considerably among women aged between 15 and 49 years since the previous estimates based on BDHS data. Frequent TV watching was associated with a higher risk of being obese among adult women in rural areas.

Association between depression and fruit and vegetable consumption among adults in South Asia

BACKGROUND

In recent years there has been a growing research interest regarding the impact of dietary behaviour on mental health outcomes. The present study aimed to investigate the association between fruit and vegetable (F&V) consumption and depression in three south Asian countries- Bangladesh, India and Nepal.

METHODS

Cross-sectional data were obtained from World Health Survey of WHO conducted during 2002-04. In total 14,133 adult subjects (Bangladesh 3262, India 7594, Nepal 3277) aged 18 years and above were included in the study. Outcome variables were Self-Reported Depression (SRD) during last 30 days and 12 months. Multivariable regression methods were used to explore the association between F&V consumption and depression.

RESULTS

Prevalence of Self-Reported Depression during past 12 months were respectively 39%, 17.7%, and 49.9% for Bangladesh, India and Nepal. In India, those who consumed less than five servings of vegetables were respectively 41% [AOR = 1.41; 95%CI = 0.60-3.33] and 57% [AOR = 1.57; 95%CI = 0.93-2.64] more likely to report severe-extreme and mild-moderate depression during past 30 days compared to those who consumed five servings a day. Regarding fruit consumption, compared to those who consumed five servings a day, the odds of severe-extreme and mild-moderate SRD were respectively 3.5 times [AOR = 3.48; 95%CI = 1.216-10.01] and 45% [AOR = 1.44; 95%CI = 0.89-2.32] higher in Bangladesh, and 2.9 times [AOR = 2.92; 95%CI = 1.12-7.64] and 42% higher [AOR = 1.41; 95%CI = 0.89-2.24] in Nepal compared to those who consumed less than five servings a day during last 30 days.

CONCLUSION

Daily intake of less than five servings of F&V was associated with higher odds of depression. Nutrition programs aimed at promoting F&V consumption might prove beneficial to reduce the prevalence of depression in south Asian population. Further studies are required to understand the factors limiting the adequate consumption of F&V.

Lifestyle Behaviors, Subjective Health, and Quality of Life Among Chinese Men Living With Type 2 Diabetes

The aim of the present study was to investigate the association between self-reported health (SRH) and quality of life (QoL) with five lifestyle-related behaviors including tobacco smoking, drinking alcohol, physical activity status, consumption of fruits, and consumption of vegetables among men diagnosed with type 2 diabetes. Participants were 786 Chinese men older than 40 years and living in urban households. Cross-sectional data on self-rated health, associated sociodemographics, and health-related behaviors were collected from the Study on Global AGEing and Health (Wave 1) of World Health Organization. Results of multivariable regression reported significant association with adherence to healthy lifestyle behavior and SRH but not QoL. According to the results, percentage of men who reported being in good SRH was overwhelmingly high (95.9%) compared with good QoL (5%). Adherence to healthy behavior was strongly associated with SRH in both bivariate and multivariate analysis, adjusted odds ratio (95% confidence interval) of good SRH for nonsmokers: 1.276 [1.055, 2.773], nondrinkers:1.351 [1.066, 3.923], taking physical exercise: 1.267 [1.117, 3.109], consuming at least five servings of fruits: 1.238 [1.034, 6.552], and vegetables: 1.365 [1.032, 3.885]. The current findings suggest that abstention from tobacco and alcohol, optimum consumption of fruits and vegetables, regular physical exercise could have marked impact on the health status of diabetic men.

Anemia Status in Relation to Body Mass Index Among Women of Childbearing Age in Bangladesh

Undernutrition and micronutrient deficiency disorders together constitute a major public health concern in Bangladesh. Among many vitamin and mineral deficiency diseases, iron-deficiency anemia remains the most persistent and has been shown to contribute to high maternal and child morbidity and mortality in the country. In parallel with micronutrient malnutrition, the country is also experiencing a rising epidemic of overweight and obesity due to changing pattern in dietary behavior and body mass index status. Previous empirical studies have demonstrated a strong correlation between body weight and anemia status. However, results remain inconclusive and for Bangladesh such evidence is nonexistent. To this end, we conducted this study using Bangladesh Demographic and Health Survey 2011 data with an aim to explore the association between body mass index and anemia status among adult women in Bangladesh. According to the findings, age between 15 and 29 years ( P < .001, OR = 1.30, 95% CI = 1.12-1.49), experiencing first birth before reaching the age of 18 years ( P < .001, OR = 1.31, 95% CI = 1.15-1.50), lack of access to potable water ( P = .013, OR = 1.467, 95%CI = 1.085- 1.982), being underweight ( P < .001, 95% CI = 1.208-1.570) and normal weight ( P < .001, 95% CI = 1.819-2.516) were significantly associated with anemia status.

Association between food insecurity and anemia among women of reproductive age

Background: Food insecurity and hidden hunger (micronutrient deficiency) affect about two billion people globally. Household food insecurity (HFI) has been shown to be associated with one or multiple micronutrient (MMN) deficiencies among women and children. Chronic food insecurity leads to various deficiency disorders, among which anemia stands out as the most prevalent one. As a high malnutrition prevalent country, Bangladesh has one of the highest rates of anemia among all Asian countries. In this study, we wanted to investigate for any association exists between HFI and anemia among women of reproductive age in Bangladesh.

Methodology: Information about demographics, socioeconomic and anemia status on 5,666 married women ageing between 13 and 40 years were collected from a nationally representative cross-sectional survey Bangladesh Demographic and Health Survey (BDHS 2011). Food security was measured by the Household Food Insecurity Access Scale (HFIAS). Capillary hemoglobin concentration (Hb) measured by HemoCue® was used as the biomarker of anemia. Data were analysed using cross-tabulation, chi-square tests and multiple logistic regression methods.

Results: Anemia prevalence was 41.7%. Logistic regression showed statistically significant association with anemia and type of residency (p = 0.459; OR = 0.953, 95%CI = 0.840–1.082), wealth status (Poorest: p < 0.001; OR = 1.369, 95%CI = 1.176–1.594; and average: p = 0.030; 95%CI = 1.017–1.398), educational attainment (p < 0.001; OR = 1.276, 95%CI = 1.132–1.439) and household food insecurity (p < 0.001; 95%CI = 1.348–1.830). Women who reported food insecurity were about 1.6 times more likely to suffer from anemia compared to their food secure counterparts.

Conclusion: HFI is a significant predictor of anemia among women of reproductive age in Bangladesh. Programs targeting HFI could prove beneficial for anemia reduction strategies. Gender aspects of food and nutrition insecurity should be taken into consideration in designing national anemia prevention frameworks.
