Nutritional assessment among adult patients with suspected or confirmed active tuberculosis disease in rural India

Nutritional status and associated factors among adult tuberculosis patients in public health centres of Horro Guduru Wollega Zone, Oromia Region, Western Ethiopia

This study aimed to assess nutritional status and associated factors among adult tuberculosis patients in public health centres in Horro Guduru Wollega Zone, Western Ethiopia, 2021. An institutional-based cross-sectional study was conducted among 334 randomly selected adult TB patients at public health centres from May 7, 2021, to June 21, 2021. Data were collected using structured questionnaires and anthropometric measurements. The nutritional status was measured by using body mass index (BMI). Data was entered into EpiData version 4.6 and exported to SPSS version 25 for analysis. A bivariate and multivariable multinomial logistic regression analysis was done to identify factors associated with nutritional status. The prevalence of under and overnutrition was found to be 48.2% and 8.7%, respectively. Female TB patients (AOR = 3.48, 95% CI: (1.918-6.314)), patients who didn't receive dietary counselling (AOR = 2.51, 95% CI: (1.335-4.720)), TB patients on the initiation phase of treatment (AOR = 3.76, 95% CI: (2.072-6.852)), and meal frequency less than three times per day (AOR = 3.6, 95% CI: (1.942-6.676)) were significantly associated with under nutrition. The prevalence of undernutrition was high in the study area. Being a female, being in the initiation phase of treatment, lack of dietary counselling, and having meal less than three per day were independently associated with undernutrition. Hence, regular nutritional assessments, dietary counselling, and nutritional support should be encouraged at the facility and community level.

Dietary patterns and micronutrients in respiratory infections including COVID-19: a narrative review

BACKGROUND

COVID-19 is a pandemic caused by nCoV-2019, a new beta-coronavirus from Wuhan, China, that mainly affects the respiratory system and can be modulated by nutrition.

METHODS

This review aims to summarize the current literature on the association between dietary intake and serum levels of micronutrients, malnutrition, and dietary patterns and respiratory infections, including flu, pneumonia, and acute respiratory syndrome, with a focus on COVID-19. We searched for relevant articles in various databases and selected those that met our inclusion criteria.

RESULTS

Some studies suggest that dietary patterns, malnutrition, and certain nutrients such as vitamins D, E, A, iron, zinc, selenium, magnesium, omega-3 fatty acids, and fiber may have a significant role in preventing respiratory diseases, alleviating symptoms, and lowering mortality rates. However, the evidence is not consistent and conclusive, and more research is needed to clarify the mechanisms and the optimal doses of these dietary components. The impact of omega-3 and fiber on respiratory diseases has been mainly studied in children and adults, respectively, and few studies have examined the effect of dietary components on COVID-19 prevention, with a greater focus on vitamin D.

CONCLUSION

This review highlights the potential of nutrition as a modifiable factor in the prevention and management of respiratory infections and suggests some directions for future research. However, it also acknowledges the limitations of the existing literature, such as the heterogeneity of the study designs, populations, interventions, and outcomes, and the difficulty of isolating the effects of single nutrients from the complex interactions of the whole diet.

Nutritionally acquired immunodeficiency must be addressed with the same urgency as HIV to end tuberculosis

Tuberculosis (TB) is the leading infectious killer worldwide, with 10.6 million cases and 1.6 million deaths in 2021 alone. One in 5 incident TB cases were attributable to malnutrition, more than double the fraction attributed to HIV. Like HIV, malnutrition is a cause of secondary immunodeficiency and has even been dubbed nutritionally acquired immunodeficiency syndrome (N-AIDS). However, malnutrition remains the neglected cousin of HIV in global TB elimination efforts. Malnutrition increases the risk for TB progression, increases disease severity, and worsens TB treatment outcomes. Thus, it is both a TB determinant and comorbidity. In this perspective, we discuss decades of data to make the case that N-AIDS, just like HIV/AIDS, also deserves special consideration in the TB elimination discourse. Fortunately, malnutrition is a modifiable risk factor and there is now empirical evidence that addressing nutrition can help us curb the TB pandemic. Recognizing malnutrition as a key determinant and comorbidity is key to detecting and treating the missing millions while also preventing additional millions from suffering TB disease.

A Review on Dietary Patterns and Double Burden of Malnutrition: Knowledge Gaps for Future Research

Nutrition transition is characterized by shifts in dietary patterns (DPs) and is one of the factors associated with the double burden of malnutrition (DBM). Evidence indicates correlations between DPs and obesity, diabetes, and cardiovascular diseases. However, little is known on how DP influences DBM. This mini-review examined DP-DBM relationship among adults along with different DP approaches and DBM definitions. A structured search of peer-reviewed articles was performed from Web of Science. Keywords related to "dietary patterns," "double burden of malnutrition," and "adults" were used. A total of 133 studies were included. Results showed that factor analysis was the predominant DP analysis method. DBM was frequently assessed at the national level and defined as the coexistence of overweight/obesity and underweight. From the 133 studies, only four articles investigated DP-DBM association and suggested that healthier DPs positively improved DBM. Significant knowledge gaps remain, including (1) application of a combination of DP approaches, (2) evaluation of individual-level and household-level DBM, and (3) inconsistency of micronutrient deficiencies and non-communicable disease indicators in DBM definition. This review revealed paucity of studies on the nexus of DPs and DBM. Future research is imperative to establish evidence on the link between food patterns and multiple burdens of malnutrition.

The Double Burden of Malnutrition at the Individual Level Among Adults: A Nationwide Survey in the Philippines

Introduction: Double burden of malnutrition (DBM) is a fast-evolving public health challenge. The rising prevalence of obesity and diet-related non-communicable diseases alongside persistent nutritional deficiencies are compelling problems in many developing countries. However, there is limited evidence on the coexistence of these conditions in the same individual among community-dwelling adults. This cross-sectional study describes the various forms of DBM and examines the determinants of DBM at the individual level among adults in the Philippines. Materials and Methods: A nationwide dataset from the 2013 Philippine National Nutrition Survey was used. The final study sample consisted of 17,157 adults (8,596 men and 8,561 non-pregnant and non-lactating women). This study focused on three DBM types within adults: (#1) Underweight and at least one cardiometabolic risk factor (Uw + ≥1 CMRF), (#2) Anemia and at least one cardiometabolic risk factor (An + ≥1 CMRF), (#3) Vitamin A deficiency or iodine insufficiency and at least one cardiometabolic risk factor (Other MND + ≥1 CMRF). The total double burden of malnutrition was also evaluated as the sum of the aforementioned three types. Logistic regression models were used to assess associations between socio-demographic and lifestyle factors and DBM. Results: The prevalence of the three types of DBM were: type #1, 8.1%; type #2, 5.6%; type #3, 20.6%, and the total DBM prevalence was 29.4%. Sex, age, educational attainment, employment status, wealth quintile, and alcohol drinking were the risk factors for DBM. In contrast, marital status, smoking, and physical activity were associated with the different DBM types. Conclusion: The study findings contribute to the current state of knowledge on the broad spectrum of individual-level DBM. Understanding the disparities of this phenomenon could guide integrated actions directed to the concomitance of malnutrition in various forms and cardiometabolic disease risks.

Prevalence and Determinants of the Co-Occurrence of Overweight or Obesity and Micronutrient Deficiencies among Adults in the Philippines: Results from a National Representative Survey

The double burden of malnutrition (DBM) affects many low- and middle-income countries. However, few studies have examined DBM at the individual level, or undernutrition and overnutrition co-occurring within the same person. This study aims to investigate the prevalence and determinants of DBM among adults in the Philippines. Data from the 2013 National Nutrition Survey were used. The sample size in the analysis was 17,010 adults aged ≥20 years old, after excluding pregnant and lactating women. DBM was defined as the co-occurrence of overweight/obesity and anemia (definition #1), overweight/obesity and anemia or vitamin A deficiency (definition #2), and overweight/obesity and anemia or vitamin A deficiency or iodine insufficiency (definition #3). Anthropometric measurements and biochemical markers were used for DBM assessment. Data were analyzed using descriptive statistics, the chi-square test, and logistic regression by R software. Results showed that definition #3 is the predominant type of DBM (7.0%) in the general population, whereas the prevalence of DBM has increased to 23.7% in overweight/obese persons. Sex, age, educational attainment, marital status, household size, wealth quintile, and smoking status were the determinants of DBM. This study revealed that Filipino adults experience malnutrition critically and must be addressed through food and nutrition interventions.

Utilisation of nutritional support scheme among the patients of tuberculosis: A myth or a truth

INTRODUCTION

Under-nutrition increases the susceptibility to active tuberculosis and delays recovery. Nikshay Poshan Yojana provides a financial incentive of Rs. 500/month for each notified TB patient for a duration until the patient is on anti-TB treatment.

OBJECTIVES

1. To find out the utilization of the nutritional support scheme among TB patients. 2. To give evidence-based recommendations.

METHODS

It is a retrospective cross-sectional study conducted among TB patients. 2 DMC's in each of the 2TU (randomly selected from 12 TUs) were chosen. 83 patients responded to telephonic interview out of all patients registered in the last six months. The demographic details were collected from TB treatment cards and registers and other information by telephonic interview of 10-15 min each conducted over a period of 15-20 days. The quantitative data thus collected was analysed in terms of frequency, percentage and Chi-square test and qualitative data from patients and providers were analysed by thematic analysis.

RESULTS

Majority were of 40-60 years of age and were males. A total of 76 patients were aware of the scheme but only 17 patients had received their first instalment after two months in their account. Among the 17 who faced difficulty while getting the money, 13 TB patients spent it on nutrition. Lack of communication, stigma, unawareness, ignorance, illiteracy, multistep approval process and technical issues were few themes that emerged as difficulties encountered while utilisation.

CONCLUSION

There is a large gap between demand and supply chain of services. A majority were unsatisfied and thus the administrative scale up for proper implementation of services and measures to bring down the stigma attached with the disease was recommended.
