Socioeconomic factors and cervical cancer mortality in Spain during the period 1989?1997

subject

description

A study was made of cervical cancer (CC) mortality trends in Spain during the period 1989–1997 at National, Autonomous Community and Provincial levels, in relation to different socioeconomic factors. Data were obtained from the Spanish National Institute of Statistics (Instituto Nacional de Estadistica, INE). The crude mortality rates were age-adjusted using the indirect method and Gross Domestic Product (GDP) as socioeconomic status (SES) indicator. National CC age-adjusted mortality rates have increasing slightly, varying from 3.09 deaths/100,000 women in 1989 to 3.42 in 1996. The highest age-adjusted mortality rates corresponded to Seville, Palencia and Orense, with 4.13, 4.06 and 3.98 cases/100,000 women, respectively. The lowest mortality rates were found in Las Palmas, Cantabria and Alicante with 2.63, 2.77 and 2.80 deaths/100,000 women, respectively. A relative risk (RR) of 1.14 (95%CI: 0.98–1.32) (P=0.048) was observed between the provinces with the lowest SES and highest mortality rate, and those with the highest SES and lowest mortality rate. The results of our study show a slight increasing trend in CC mortality rates in Spain during the period 1989–1997, and suggest that the variations among provinces and Autonomous Communities could be due to CC risk factors (SES related to human papillomavirus, parity, diet, etc.) and differences in early diagnosis.
