An Overview of Infant Mortality Trends in Qatar from 2004 to 2014

The impact of sociodemographic, health status and resources, macroeconomic, and environmental factors on infant mortality rates in Qatar, Kingdom of Saudi Arabia, and the United Arab Emirates

OBJECTIVES

This study aims to study the impact of sociodemographic (SD), health status and resources (HSR), macroeconomic (ME), and Environmental (EV) factors on the infant mortality rate (IMR) in Qatar, Kingdom of Saudi Arabia (KSA), and the United Arab Emirates (UAE) and from 1990 to 2022.

DESIGN

A retrospective time-series study employing yearly data was conducted. A generalized least squares model was utilized to construct an exploratory model of IMR determinants for each country.

RESULTS

In SD, the risk of IMR may be increased with a higher crude birth rate, adolescent fertility rate, and married women percentage. In HSR, immunization coverage shows a significant effect in preventing neonatal diseases and reducing IMR. In ME, the effect of parents' employment seems contradicted among the three countries. In EV, greenhouse emissions have also had contradictory effects among the three countries, suggesting a complex relationship with IMR. Some were consistent with global findings, whereas others contradicted the prevailing narrative.

CONCLUSIONS

This study highlights the need for tailored public health interventions addressing socio-demographic, healthcare, and environmental contexts to effectively reduce IMR and enhance infant health outcomes.

Core health indicators in countries with high proportion of expatriates: Case study of Qatar

Background

Population size and structure have a huge impact on health indicators. In countries with a high proportion of expatriates, there are some limitations in estimating, aggregating and reporting of the health indicators, and corrections may be required in the established estimation methodologies. We review the case of Qatar to see how its specific population characteristics affect its health indicators.

Methods

We used routinely collected data and reviewed and calculated a selected list of health indicators for Qatari and non-Qatari populations residing in Qatar. Mortality and cancer incidence rates, stratified by nationality, were used for this purpose. Also, a direct method was used to estimate completeness of the death registry, compared to the mortuary data.

Results

Age and sex distribution of Qatari and non-Qatari populations are completely different. Compared to the mortuary data, completeness of death registration for the total population was estimated at 98.9 and 94.3%, with and without considering overseas deaths, respectively. Both estimates were considerably higher than estimates from the indirect methods. Mortality patterns were different even after standardization of age and stratification of sex groups; male age-standardized mortality rates were 502.7 and 242.3 per 100,000 individuals, respectively for Qataris and non-Qataris. The rates were closer in female populations (315.6 and 291.5, respectively). The leading types of cancer incidents were different in Qataris and non-Qataris.

Conclusions

Expatriates are a dynamic population with high-turnover, different from Qatari population in their age-sex structure and health status. They are more likely to be young or middle-aged and are less affected by age related diseases and cancers. Also, they might be at higher risks for specific diseases or injuries. Aggregating indicators of Qatari and non-Qatari populations might be mis-leading for policy making purposes, and common estimation correction approaches cannot alleviate the limitations. High-proportion of expatriate population also imposes significant errors to some of the key demographic estimates (such as completeness of death registry). We recommend a standardized approach to consider nationality in addition to age and sex distributions for analysis of health data in countries with a high proportion of expatriates.

Trends in the leading causes of childhood mortality from 2004 to 2016 in Qatar

Introduction

Childhood mortality is an important health indicator that reflects the overall health status of a population. Despite the decrease in global childhood mortality rates over the past decades, it still remains an important public health issue in Qatar.

Methods

The data from 2004-2016 were extracted from the Qatar Ministry of Public Health Birth and Death Database. International Classification of Diseases (ICD-10) was used for coding the causes of death. The childhood mortality rate was defined as the probability of a child dying between the first and the fifth birthday, expressed as the number of deaths per 1,000 children surviving to 12 months of age. The sex ratio was calculated by dividing the mortality rate of males by that of females. Mann-Kendall trend test was performed to examine time trends. Relative risks were calculated to examine differences by nationality (Qatari and non-Qatari) and sex.

Results

A significant decrease in mortality rate of children aged one to five was observed from 1.76 to 1.05 per 1000 children between 2004 and 2016 (Kendall tau=-0.6, p=0.004). Three prominent causes of mortality were motor vehicle accidents, congenital malformations of the circulatory system, and accidental drowning/submersion. A statistically non-significant decrease in childhood mortality from motor vehicle accidents was oberved for all nationalities (total (Kendall tau=-0.03), Qatari (Kendall tau=-0.14), and non-Qatari (Kendall tau=-0.12)). A significant decrease was seen for total accidental drowning and submersion (Kendall tau=-0.54, p=0.012), while no statistically significant decrease was seen for total congenital malformations of the circulatory system (Kendall tau=-0.36, NS). The Qatari population did have a significant decrease in childhood mortality due to congenital malformations of the circulatory system (Kendall tau=-0.67, p=0.003) and accidental drowning and submersion (Kendall tau=-0.55, p=0.016).

Conclusion

The study is a first attempt to evaluate childhood mortality statistics from Qatar and could be useful in supporting Qatar's ongoing national health strategy programs.
