Information given to women invited for cervical screening: results of two postal surveys seven years apart.
In South Staffordshire, England, we compared women's views on information provided to them at different stages of the cervical screening program in 1994 with that provided in 2001. An age-stratified random sample of women aged 20-64 years who had a cervical smear taken between January and March 1994 (3856) or between January and March 2001 (4057) were sent postal questionnaires in June 1994 and July 2001, respectively. Response rates in 1994 (3124/3856, 81%) and 2001 (3288/4057, 81%) were similar. Compared to 1994, the proportion of women who thought the invitation letter was clear to read in 2001 increased (70% vs 98%, P < 0.0001); however, letters were thought to be less reassuring in 2001 compared to 1994 (P < 0.0001). In both study periods, 66% of women reported that the procedure was explained to them before the smear was taken. A greater proportion of women received their results by letter in 2001 compared to 1994 (57% vs 41%, P < 0.0001); however, 49% of women waited >4 weeks to receive their results in 2001 compared to 26% in 1994 (P < 0.0001). Bivariate analysis suggests that responses were age related, with older women (> or =45 years) experiencing poorer information provision. The issues highlighted by this study deserve further investigation in other areas.

Seroepidemiology of hepatitis A infection in India: changing pattern.
OBJECTIVE: Recent changes in the epidemiology of hepatitis A virus (HAV) infection and the availability of effective vaccines have renewed interest in this infection. We determined the age-related prevalence of anti-HAV antibodies in India and looked for differences by known risk factors for HAV infection. METHODS: In this prospective study, serum samples obtained from 1612 subjects aged 1 to 60 at six centers in five cities (Calcutta, Cochin, Indore, Jaipur and Patna) during the period February to August 1998 were tested for anti-HAV antibodies. Demographic and socio-economic information was obtained by questionnaire. RESULTS: The overall seroprevalence rate was 65.9%, varying from 26.2% to 85.3% in various cities; there was no difference between males and females. Seropositivity increased with age from 52.2% in the 1-5 year age group to 80.8% in those aged 16 years or more. Seroprevalence rates were significantly lower in those aged 1-5 years compared with other age groups (p<0.0001). There was no difference in seroprevalence between those with monthly family income Rs 5001. Multivariate analysis showed that anti-HAV seroprevalence varied significantly by source of water supply, being highest when the supply was municipal. CONCLUSION: Our results indicate an epidemiological pattern of intermediate endemicity. This finding has public health implications as it indicates that a significant proportion of the Indian adolescent and adult population is at risk of HAV infection.
