Abstract
Background: The reduction of child and adolescent deaths (defined as decedents aged 0–19 years) remains a crucial public health priority also in high-income countries such as Finland. There is evidence of a relationship between socioeconomic gradients and child mortality, but the association is considered complex and relatively poorly understood. Exploiting a Finnish dataset with nationwide coverage, the present study aimed to shed light on the sociodemographic predictors of child and adolescent mortality at the municipality level.Methods: A public database of Statistics Finland was queried for municipality-level data on sociodemographic traits and child and adolescent deaths in Finland during the years 2011–2018. The sociodemographic indicators included total population size, child and adolescent population size, sex distribution, mean age, education, unemployment, median income, population density, rurality, percentage of individuals living in their birth municipality, household size, overcrowded households, foreign language speakers, divorce rate, car ownership rate, and crime rate. The sociodemographic indicators were modeled against child and adolescent mortality by means of generalized estimating equations.Results: A total of 2,371 child and adolescent deaths occurred during the 8-year study period, yielding an average annual mortality rate of 26.7 per 100,000 individuals. Despite a fluctuating trend, the average annual decline in child and adolescent deaths was estimated to be 3% (95% confidence interval 1–5%). Of the sociodemographic indicators, population density was associated with higher child and adolescent mortality (rate ratio 1.03, 95% confidence interval 1.01–1.06), whereas the percentage of foreign language speakers was associated with lower child and adolescent mortality (0.96, 0.93–0.99).Conclusion: Densely populated areas should be the primary focus of efforts to reduce child and adolescent mortality. Of note is also the apparently protective effect of foreign language speakers for premature mortality. Future studies are welcomed to scrutinize the mediating pathways and individual-level factors behind the associations detected in this study.
Highlights
Child well-being is a key public health priority [1], and child mortality is commonly used as an economic and social welfare indicator [2, 3]
During the study period 2011–2018, the annual number of child and adolescent deaths fluctuated between 247 and 358 cases (Supplementary Table 2; Supplementary Figure 1). Both the number of deaths and mortality rate showed a decline of 3% per year (Supplementary Figure 1; Table 2)
In the full multivariable model, where the internal dependencies within the dataset were controlled for, population density was associated with higher child and adolescent mortality, and the percentage of foreign language speakers was associated with lower child and adolescent mortality (0.96, 0.93–0.99)
Summary
Child well-being is a key public health priority [1], and child mortality is commonly used as an economic and social welfare indicator [2, 3]. The reduction of child and adolescent mortality remains a crucial public health priority in high-income countries [7, 8]. While the association between social inequality and child mortality is widely prevalent in lowand middle-income countries [10], a similar relationship seems to persist in high-income countries such as Canada [11], the USA [12], and England [13]. The reduction of child and adolescent deaths (defined as decedents aged 0–19 years) remains a crucial public health priority in high-income countries such as Finland. Exploiting a Finnish dataset with nationwide coverage, the present study aimed to shed light on the sociodemographic predictors of child and adolescent mortality at the municipality level
