Abstract [sv]

Abstrakt Bakgrund: DMFT (Decayed, Missing, Filled Tooth) har minskat i många delar av världen under det senaste århundradet. Resultat från flera studier visar att DMFT kan vara beroende av socioekonomiska faktorer. Emellertid har de flesta studierna bara granskat några faktorer och på subnationell nivå medan studier på global nivå saknas. Syfte: Att undersöka om det finns ett samband mellan kariesminskning och socioekonomiska faktorer. Material och metod: Socioekonomiska faktorer har valts och data för varje variabel har erhållits med hjälp av World Bank. DMFT-värdena mellan 1960–2017 för olika stater och provinser har erhållits från Oral Health Country/area Profile Project (CAPP). Endast perioder då kariesminskning har inträffat inkluderades. DMFT har fastställts som en beroende variabel och socioekonomiska faktorer som oberoende variabler där linjär regression användes för att analysera insamlad data. P-värdet sattes till 0,05. Tidigare studier och forskning inom ämnet användes för att formulera hypoteser. Resultat: Totalt 6 st variabler visades ha samband med DMFT under perioder av kariesminskning och följande värden för signifikansen erhölls för dessa variabler: Fattigdom (p=0,027), Gini (6x 10-6), andel av jordbruk i Bruttonationalproduken (BNP) (p=0,017), andel av industri i BNP (p=7x10-7), förväntad livslängd (p=1,35x10-4), sockerkonsumtion (p=0,012). Bland de variabler som inte har visats samband med DMFT under perioder av kariesminskning erhölls följande värden av DMFT: BNP per capita (p=0,440), BNP per capita tillväxt per år (p=0,419), arbetslöshet (p=0,699), läskunnighet (p=0,304). Slutsats: De oberoende variablerna fattigdom, Gini, andel av industrin i BNP, andel av jordbruk i BNP och sockerkonsumtion hade en korrelation med DMFT, där större värde på dessa parametrar innebar ett högre DMFT under perioder då det skedde kariesminskning. Livslängden hade ett omvänt samband dvs ju större värde på livslängden, desto mindre DMFT under motsvarande perioder. BNP per capita, årlig BNP-tillväxt per capita, arbetslöshet och läskunnighet hade ingen korrelation med DMFT-värdena under de perioder det skedde kariesminskning.

Abstract Background: The index Decayed, Missing, Filled, Tooth (DMFT) has declined in many parts of the world in the last century. Results from several studies indicate that DMFT can be dependent of socioeconomic factors. However, most of the studies have only examined a few factors and on a subnational level while studies on a global scale are lacking. Aim: The aim of this study was to investigate whether there is a correlation between caries decline and socio-economic factors. Material and method: Socioeconomic factors have been chosen and the data for each variable have been obtained using World Bank. DMFT- value between 1960-2017 for various states and provinces has been obtained using Oral Health Country/area Profile Project (CAPP). Only periods of time when decline of caries has occurred were included. Linear regression was used to analyze data. DMFT has been set as a dependent variable and socioeconomic factors as independent variables. P-value was set to 0.05. Previous studies and research in the subject were used to formulate hypotheses. Results: A total of six variables proved to have a correlation with DMFT during periods of caries decline, and the following statistical significance values were obtained for these variables: Poverty rate (p=0.027), Gini (6x 10-6), share of agriculture in Gross Domestic Product (GDP) (p=0.017), share of industry in GDP (p=7x10-7), life expectancy (p=1.35x10-4), sugar consumption (p=0.012). Among variables proved not to have a correlation with DMFT during periods of caries decline, the following significance values were obtained: GDP per capita (p=0.440), annual growth of GDP per capita (p=0.419), unemployment rate (p=0.699), literacy rate (p=0.304). Conclusion: The independent variables poverty rate, Gini, share of industry in GDP, share of agriculture in GDP and sugar consumption had a positive correlation with DMFT. That means the higher value of these variables, the higher DMFT, during the timespans of caries decline. Life expectancy had a conversely correlation during corresponding periods. GDP per capita, annual growth of GDP per capita, unemployment rate and literacy rate had no correlation with the DMFT-value, during periods of caries decline.
