A retrospective analysis of the association between tobacco smoking and deaths from respiratory and cardiovascular diseases in the Kassena-Nankana districts of Northern Ghana

Respiratory-related deaths and associated factors in Alicho-Weriro district, southern Ethiopia: verbal autopsy data analysis

BACKGROUND

Respiratory diseases disproportionately affect people living in resource-limited settings. However, obtaining information that explains respiratory-related deaths has been difficult, mainly due to a lack of medical certification of death and the fact that most deaths occur outside of health institutions. This study aimed to determine the proportion of respiratory-related deaths and identify associated factors in Alicho-Weriro district, southern Ethiopia, using the verbal autopsy method.

METHODS

A community-based cross-sectional study was conducted from April to June 2022. All deceased people in the study area from January 2020 to December 2021 were included in the study. Trained physicians ascertained the cause of death from verbal autopsy data that were collected using a pre-tested and modified WHO-designed questionnaire. The binary logistic regression models were used to identify factors associated with respiratory-related deaths.

RESULTS

Respiratory-related deaths accounted for 25% of the deaths from all causes, with 20.8% of male and 29.5% of female deaths. Of which, 9.7% were from tuberculosis, 8.3% were from asthma and 6.2% were from acute lower-respiratory tract infections. Moreover, being female (adjusted OR, AOR: 3.3; 95% CI: (1.75 to 6.22)), age 50-64 years (AOR: 9.3; 95% CI: (1.16 to 73.90)), age above 64 years (AOR: 8.9; 95% CI: (1.130 to 70.79)), family size of five persons or more (AOR: 1.9; 95% CI: (1.15 to 3.29)), smoking (AOR: 3.9; 95% CI: (1.86 to 8.35)), using wood and/or animal dung for household cooking (AOR: 6.6; 95% CI: (1.92 to 22.59)) and poor house ventilation (AOR: 3.1; 95% CI: (1.75 to 5.38)) were significantly associated with increased odds of dying from respiratory-related diseases.

CONCLUSION

This study has determined that about a quarter of deaths from all causes were due to respiratory diseases, mainly tuberculosis, asthma and acute lower respiratory tract infections. Therefore, interventions to reduce this burden should focus on supporting early case detection and treatment, promoting healthy lifestyles, exercising women's equality at the household level and improving housing conditions.

Cardiovascular disease mortality based on verbal autopsy in low- and middle-income countries: a systematic review

Objective

To conduct a systematic review of verbal autopsy studies in low- and middle-income countries to estimate the fraction of deaths due to cardiovascular disease.

Method

We searched MEDLINE®, Embase® and Scopus databases for verbal autopsy studies in low- and middle-income countries that reported deaths from cardiovascular disease. Two reviewers screened the studies, extracted data and assessed study quality. We calculated cause-specific mortality fractions for cardiovascular disease for each study, both overall and according to age, sex, geographical location and type of cardiovascular disease.

Findings

We identified 42 studies for inclusion in the review. Overall, the cardiovascular disease cause-specific mortality fractions for people aged 15 years and above was 22.9%. This fraction was generally higher for males (24.7%) than females (20.9%), but the pattern varied across World Health Organization regions. The highest cardiovascular disease mortality fraction was reported in the Western Pacific Region (26.3%), followed by the South-East Asia Region (24.1%) and the African Region (12.7%). The cardiovascular disease mortality fraction was higher in urban than rural populations in all regions, except the South-East Asia Region. The mortality fraction for ischaemic heart disease (12.3%) was higher than that for stroke (8.7%). Overall, 69.4% of cardiovascular disease deaths were reported in people aged 65 years and above.

Conclusion

The burden of cardiovascular disease deaths outside health-care settings in low- and middle-income countries is substantial. Increasing coverage of verbal autopsies in these countries could help fill gaps in cardiovascular disease mortality data and improve monitoring of national, regional and global health goals.

Health-seeking behaviour and cost of fever treatment to households in a malaria-endemic setting of northern Ghana: a cross-sectional study

OBJECTIVES

To examine the health-seeking behaviour and cost of fever treatment to households in Ghana.

DESIGN

Cross-sectional household survey conducted between July and September 2015.

SETTING

Kassena-Nankana East and West districts in Upper East region of Ghana.

PARTICIPANTS

Individuals with an episode of fever in the 2 weeks preceding a visit during routine health and demographic surveillance system data collection were selected for the study. Sociodemographic characteristics, treatment-seeking behaviours and cost of treatment of fever were obtained from the respondents.

RESULTS

Out of 1845 households visited, 21% (393 of 1845) reported an episode of fever. About 50% (195 of 393) of the fever cases had blood sample taken for testing by microscopy or Rapid Diagnostic Test, and 73.3% (143 of 195) were confirmed to have malaria. Of the 393 people with fever, 70% (271 of 393) reported taking an antimalarial and 24.0% (65 of 271) took antimalarial within 24 hours of the onset of illness. About 54% (145 of 271) of the antimalarials were obtained from health facilities.The average cost (direct and indirect) incurred by households per fever treatment was GH¢27.8/US$7.3 (range: GH¢0.2/US$0.1-GH¢200/US$52.6). This cost is 4.6 times the daily minimum wage of unskilled paid jobs of Ghanaians (US$1.6). The average cost incurred by those enrolled into the National Health Insurance Scheme (NHIS) was GH¢24.8/US$6.5, and GH¢50/US$11.6 for those not enrolled.

CONCLUSIONS

Prompt treatment within 24 hours of onset of fever was low (24%) compared with the Roll Back Malaria Programme target of at least 80%. Cost of treatment was relatively high when compared with average earnings of households in Ghana and enrolment into the NHIS reduced the cost of fever treatment remarkably. It is important to improve access to malaria diagnosis, antimalarials and enrolment into the NHIS in order to improve the case management of fever/malaria and accelerate universal health coverage in Ghana.

Global Cancer in Women: Cancer Control Priorities

This review is an abbreviated version of a report prepared for the American Cancer Society Global Health department and EMD Serono, Inc., a subsidiary of Merck KGaA, Darmstadt, Germany, which was released at the Union for International Cancer Control World Cancer Congress in Paris in November 2016. The original report can be found at https://www.cancer.org/health-care-professionals/our-global-health-work/global-cancer-burden/global-burden-of-cancer-in-women.html. Staff in the Intramural Research Department of the American Cancer Society designed and conducted the study, including analysis, interpretation, and presentation of the review. The funding sources had no involvement in the study design, data analysis and interpretation, or preparation of the reviewThe global burden of cancer in women has recently received much attention, but there are few comprehensive reviews of the burden and policy approaches to reduce it. This article, second in series of two, summarizes the most important cancer control priorities with specific examples of proven interventions, with a particular focus on primary prevention in low- and middle-income countries (LMIC). There are a number of effective cancer control measures available to countries of all resource levels. Many of these measures are extremely cost-effective, especially in the case of tobacco control and vaccination. Countries must prioritize efforts to reduce known cancer risk factors and make prevention accessible to all. Effective treatments and palliative care are also needed for those who develop cancer. Given scarce resources, this may seem infeasible in many LMICs, but past experience with other diseases like HIV, tuberculosis, and malaria have shown that it is possible to make affordable care accessible to all. Expansion of population-based cancer registries and research in LMICs are needed for setting cancer control priorities and for determining the most effective interventions. For LMICs, all of these activities require support and commitment from the global community.
