Socioeconomic inequality in tobacco expenditure in Iran: a cross-sectional analysis at national and subnational levels.

ABSTRACT:

Background

Tobacco expenditure has adverse impacts on expenditure on basic needs and resource allocation of the households. Using data from a nationally representative survey, we measured socioeconomic inequality in tobacco expenditure as the share of household budget (TEHB) and explained its main determinants among Iranian households at the national and sub-national levels.

Methods

This cross-sectional study used data from the Iranian Household Income and Expenditure Survey (IHIES), 2018. We included a total of 7649 households with tobacco expenditure more than zero in the analysis. Province-level data on the Human Development Index (HDI) was obtained from the Institute for Management Research at Radbound University. The concentration curve (CC) and the concentration index (C) were used to measure socioeconomic inequality in TEHB at national and sub-national levels. The C was decomposed to identify the factors explaining the observed socioeconomic inequality in TEHB.

Results

At the national level, households with at least one smoker spent more than 5% of their budget for tobacco consumption in the last month. Households from the urban areas allocated less of their budgets on tobacco products compared to rural households (4.6% vs. 5.8%). Overall, TEHB was more concentrated among the poorer households (C?=?0.1423, 95% CI: -?0.1552 to -?0.1301). In other words, the distribution of TEHB was pro-poor in Iran. Pro-poor inequality in TEHB was also found in urban (C = -?0.1707, 95% CI: -?0.1998 to -?0.1516) and rural (C = -?0.1314, 95% CI: -?0.1474 to -?0.1152) areas. We also found that pro-poor inequalities were higher in Iranian provinces with low HDI. The decomposition results indicate that wealth and education were the main factors contributing to the concentration of TEHB among the poorer households.

Conclusion

This study found that TEHB was disproportionality concentrated among poorer households in Iran. The extent of inequality in TEHB was higher in urban areas and less developed provinces. Designing and implementing tobacco control interventions to decrease the smoking prevalence and increase smoking cessation could protect worse-off households against the financial burden of tobacco spending.

Project description:Background:Self-medication (SM) is a public health concern globally. This study aimed to measure socioeconomic inequality in SM and identify its main determinants among Iranian households. Methods:A total of 38,859 households from the 2018 Household Income and Expenditure Survey (HIES) were included in the study. Data on SM, household size, age, gender and education status of the head of household, monthly household's expenditures (as a proxy for socioeconomic status), health insurance coverage and living areas and provinces were obtained for the survey. The concentration curve and the normalized concentration index (Cn ) were used to quantify the magnitude of socioeconomic inequality in SM among Iranian households. The Cn was decomposed to identify the main determinants of socioeconomic inequality in SM in Iran. Results:The results indicated that 18.2% (95% confidence interval [CI]: 17.7% to 18.5%) of households in Iran had SM practice in the past month. The results suggested a higher concentration of SM among the rich households (Cn = 0.0466; 95% CI= 0.0321 to 0.0612) in Iran. The concentration of SM among high SES households was also found in urban (0.0311; 95% CI=0.0112 to 0.0510) and rural (= 0.0513; 95% CI=0.0301 to 0.0726) areas. SM was concentrated among the rich households in Tehran, Qom, Esfahan, Ardebil, Golestan, and Sistan and Baluchestan provinces. In contrast, a higher concentration of SM was found among the poor households in Semnan, North Khorasan, Kerman, Bushehr, and South Khorasan provinces. The decomposition revealed SES of household, itself, as the main contributing factor to the concentration of SM among the wealthy households. Conclusion:This study demonstrated that SM is more concentrated among socioeconomically advantaged households in Iran. Thus, effective evidence-based interventions should be implemented to improve awareness about SM and its negative consequences. Further studies are required to investigate the consequences of SM practice among people.

Project description:ObjectiveThe levels, distributions of child malnutrition and its potential risk factors are not very well known in Myanmar. The objectives included in this study were: to estimate the current national and subnational prevalence of four types of malnutrition (stunting, wasting, underweight and overweight) among children under 5 in Myanmar; to identify potential risk factors associated with each type of malnutrition and to investigate how the identified risk factors' distributions explained the regional disparities in malnutrition prevalence.Design/methodsData from the Myanmar Demographic and Health Survey 2015-2016 were used to estimate the prevalence of four types of malnutrition at both national and subnational levels (15 regions). Logistic regression models were applied to examine the association between each type of malnutrition and its risk factors, including child's factors, parental social status and household conditions. The risk factor-adjusted prevalence of the malnutrition was estimated at the subnational level based on the estimated parameters from the regression models.ResultsThe national prevalence of stunting, wasting, underweight and overweight in children under 5 was estimated to be 29.1% (95% CI 27.7% to 30.6%), 6.8% (6.0% to 7.6%), 18.3% (17.0% to 19.5%) and 1.5% (1.1% to 1.9%), respectively. Substantial regional variations in the prevalence of each type of malnutrition were observed. Several risk factors of each type of malnutrition were identified, including low birth weight (LBW) and inadequate maternal nutritional status. Except for overweight, regional variations largely persisted even after adjustment for the risk factors investigated.ConclusionThe prevalence of malnutrition among children under 5 is still high in Myanmar, most commonly stunting. Targeted interventions aimed at prevention of LBW, improving the maternal nutritional status, in addition to other sociodemographic conditions should be encouraged urgently. Further research is necessary to investigate the potential sources of regional variation in prevalence of malnutrition among children under 5 in the country.

Project description:BackgroundCost, social acceptability and non-stringent regulations pertaining to smokeless tobacco (SLT) product sales have made people choose and continue using SLT. If disaggregated data on smokeless forms and smoked practices of tobacco are reviewed, the incidence of SLT remains static. There is a strong positive correlation of SLT intake with the occurrence of adverse cardiovascular disease, particularly in the low socioeconomic populations.AimsTo investigate the prevalence of smokeless tobacco, its initiation influence and risk factors associated with the practice among lower socioeconomic populations of Bangladesh. In this study, we explore the utilization of SLT among lower socioeconomic populations in industrialized zone of Bangladesh.MethodsA cross-sectional analysis using both quantitative and categorical approaches was employed. Using systematic random sampling method, four focus group discussions (FGDs) were conducted and 459 participants were interviewed. Multiple logistic regression model was applied to distinguish the significant factors among the SLT users.ResultsAlmost fifty percent of the respondents initiated SLT usage at the age of 15-24 years and another 22 percent respondents were smoking and using SLT concurrently. The bulk of the women respondents used SLT during their pregnancy. Nearly twenty five percent of the respondents tried to quit the practice of SLT and one-quarter had a plan to quit SLT in the future. More than twenty percent respondents were suffering from dental decay. A noteworthy correlation was found by gender (p<0.01), sufferings from SLT related disease (p<0.05). The multiple logistic regression analysis suggested that, males were 2.7 times more knowledgeable than that of females (p<0.01) about the adversative health condition of SLT usage. The respondents suffering from SLT related diseases were 3.7 times as more knowledgeable about the effect of the practice of SLT than the respondents without diseases (p<0.01). Regarding the knowledge about the health consequences of the practice of SLT, one participant in the FGD session commented that "although the mouth is the gateway to health, we infected our mouth by using Zarda and Gul". Again, informants opined that peer, family, curiosity and hospitality, culture are influencing factors for SLT initiation.Conclusioncounselling on tobacco, including SLT, health hazards have to be emphasized through mass media and it is essential for development of relevant policies and communication messages to make people aware of serious health consequences of SLT usages.

Project description:Failure to meet early childhood developmental milestones leads to difficulty in schooling and social functioning. Evidence on the inequality in the burden of developmental delays across population groups, and identification of potential risk factors for suspected developmental delays (SDD) among younger children, are essential for designing appropriate policies and programs. This study explored the level of socioeconomic and maternal education-based inequality in the prevalence of SDD among Nepalese children at subnational level and identified potential risk factors. Individual-level data from the 2019 Nepal Multiple Indicator Cluster Survey was used to estimate the prevalence of SDD among children aged 3-4 years. Regression-based slope index of inequality (SII) and relative index of inequality were used to measure the magnitude of inequality, in terms of household socioeconomic status (SES) and mother's education, in the prevalence of SDD. In addition, a multilevel logistic regression model was used to identify potential risk factors for SDD. The national prevalence of SDD was found to be 34.8%, with relatively higher prevalence among children from rural areas (40.0%) and those from Karnali Province (45.0%) followed by Madhesh province (44.2%), and Sudhurpashchim Province (40.1%). The prevalence of SDD was 32 percentage points higher (SII: -0.32) among children from the poorest households compared to their rich counterparts at the national level. At the subnational level, such inequality was found to be highest in Lumbini Province (SII = -0.47) followed by Karnali Province (SII = -0.37), and Bagmati Province (SII = -0.37). The prevalence of SDD was 36 percentage points higher (SII: -0.36) among children whose mother had no formal education compared to children of higher educated mothers. The magnitude of education-based absolute inequality in SDD was highest in Lumbini Province (SII = -0.44). Multilevel logistic regression model identified lower levels of mother's education, disadvantaged SES and childhood stunting as significant risk factors for SDD. One in each three children in Nepal may experience SDD, with relatively higher prevalence among children from rural areas. Subnational level variation in prevalence, and socioeconomic and education-based inequality in SDD highlight the urgent need for province-specific tailored interventions to promote early childhood development in Nepal.
