Background: The relationship between Tuberculosis (TB) and nutritional status is a significant one. Patients with TB who are underweight face a higher risk of death. Purpose: This research aims to analyze the factors related to the occurrence of being underweight among TB patients at the Public Health Center (PHC) in Perak Timur, Surabaya. Method: This was an analytical observational study and used a cross-sectional design. The sample for this research was 41 respondents, who were TB patients and were undergoing treatment at the PHC in Perak Timur, Surabaya. Data collection was done from March 2020 to June 2020. Primary data was collected by conducting interviews using a questionnaire. Data analysis was performed using a chi-square test. Results: The results indicated that, out of the 41 respondents, there were 21 respondents who were underweight (51.22%). Descriptively, underweight TB patients were more likely to be in the intensive phase of treatment (90%), have a low income (56.76%), have a low education status (65.38%), and be unemployed (59.38%), with PR=0.43 and 95%CI=0.76–9.38. The results of this research indicated a link between the treatment phase and TB patients being underweight (p=0.01; PR=2.33; 95% CI=1.43–3.79), the level of education attained by underweight TB patients (p=0.04; PR=0.41; 95% CI=0.17–0.99), and the income of underweight TB patients (p=0.04; PR=0.43; 95%CI=0.30–0.63). The results of this research indicated that there was a correlation between the work status and TB patients being underweight (p=0.07; PR=2.67; 95%CI=0.76–9.38). Conclusion: The treatment phase, education level and income are significantly related to TB patients being underweight.

Background: Asthma is ranked 16th among the leading causes of years lived with disability (YLD) and ranks 28th among the causes of global burden of disease (GBD). Various potential factors can cause asthma, which include body mass index (BMI) and gender. Purpose: This research aimed to determine the relationship between BMI and gender in people living with asthma in Indonesia. Methods: This research employed secondary data obtained from the Indonesian family life support (IFLS) 5th edition. This research used an observational analysis technique with a cross-sectional approach. The number of respondents in this research were 30,713. In this study, the BMI category was based on WHO’s classification for Asians. Data was analyzed using logistic regression tests and chi square. Statistical significance was set at a value of p<0.05. Results: As many as 17,175 respondents had a normal BMI range (56.92%), out of which the majority were women—16,001 respondents (52.10%). After controlling the other variables, statistical test results with logistic regression indicated that male respondents had 1.23 times the odds of experiencing asthma compared to females (adjusted odds ratio (AOR)=1.23; 95% confidence interval (CI), 1.04–1.44; p=0.02). Again, after controlling the other variables, underweight respondents had 1.31 times the odds of experiencing asthma compared to respondents who had a normal BMI (AOR=1.31; 95%CI=1.07–1.59; p=0.01). Conclusion: A relationship between gender and the category of people who were underweight after determining their BMI could be established. Health counseling can be provided to help improve the respiratory conditions of these individuals.
