Single-visit approach of cervical cancer screening: see and treat in Indonesia.

BACKGROUND: We performed a cross-sectional study in Indonesia to evaluate the performance of a single-visit approach of cervical cancer screening, using visual inspection with acetic acid (VIA), histology and cryotherapy in low-resource settings. METHODS: Women having limited access to health-care facilities were screened by trained doctors using VIA. If the test was positive, biopsies were taken and when eligible, women were directly treated with cryotherapy. Follow-up was performed with VIA and cytology after 6 months. When cervical cancer was suspected or diagnosed, women were referred. The positivity rate, positive predictive value (PPV) and approximate specificity of the VIA test were calculated. The detection rate for cervical lesions was given. RESULTS: Screening results were completed in 22 040 women, of whom 92.7% had never been screened. Visual inspection with acetic acid was positive in 4.4%. The PPV of VIA to detect CIN I or greater and CIN II or greater was 58.7% and 29.7%, respectively. The approximate specificity was 98.1%, and the detection rate for CIN I or greater was 2.6%. CONCLUSION: The single-visit approach cervical cancer screening performed well, showing See and Treat is a promising way to reduce cervical cancer in Indonesia.

Parental acceptance of human papillomavirus (HPV) vaccination in Indonesia: a cross-sectional study.

BACKGROUND: Cervical cancer ranks the second most frequent cancer in Indonesian women. In Indonesia, human papillomavirus (HPV) vaccine acceptance has not been studied before. OBJECTIVE: To determine parental HPV vaccine acceptance in Indonesia, and factors that influence their decision. Factors include sociodemographic factors, knowledge of HPV, HPV vaccination and cervical cancer, health beliefs about cervical cancer, and attitudes towards vaccination in general. METHODS: 746 parents, with at least 1 daughter aged 0-14, were interviewed using questionnaires based on published and adjusted interviews. Interviews were done in sub district public health centers, general governmental hospitals, and via house-visits, in 5 Indonesian provinces. RESULTS: Parental HPV vaccine acceptance was 96.1%. Logistic regression revealed that age, beliefs regarding cervical cancer, and attitudes towards vaccination in general were significantly associated with HPV vaccine acceptance. Of the participants, 66.0%, 16.6%, and 15.8% had heard about cervical cancer, HPV, and HPV vaccination respectively. The mean total knowledge score was 1.91(Standard Deviation 2.31) on a 0-8 scale. Health beliefs about cervical cancer and attitudes towards vaccination in general were positive. Participants named the high cost of the vaccine, fear for side-effects, and chosen vaccination locations as possible barriers towards HPV vaccine implementation. DISCUSSION: Parental HPV vaccine acceptance is high, but knowledge about HPV and cervical cancer is low. During HPV vaccination programs, focus should not only be on providing information, but also on existing beliefs and attitudes towards cervical cancer and vaccination in general. If HPV vaccination programs were to be implemented in Indonesia, the indicated barriers should be taken into account.

Prevalence of human papillomavirus in Indonesia: a population-based study in three regions.

Cervical cancer is the most common cancer among women in the Indonesian population, yet little is known about the prevalence of human papillomavirus (HPV). We investigated age-specific prevalence of HPV types and possible risk factors of HPV positivity in a population-based sample of 2686 women, aged 15-70 years, in Jakarta, Tasikmalaya, and Bali, Indonesia. The overall HPV prevalence was 11.4%, age-standardized to the world standard population 11.6%. The most prevalent types found were HPV 52, HPV 16, HPV 18, and HPV 39, respectively, 23.2, 18.0, 16.1, and 11.8% of the high-risk HPV types. In 20.7% of infections, multiple types were involved. Different age-specific prevalence patterns were seen: overall high in Jakarta, and in Tasikmalaya, and declining with age in Bali. The number of marriages was most associated with HPV positivity (OR 1.81 95% CI 1.31-2.51)). Remarkably, in Indonesia HPV 16 and HPV 18 are equally common in the general population, as they are in cervical cancer. HPV 52 was the most prevalent type in the general population, suggesting that this type should be included when prophylactic HPV vaccination is introduced in Indonesia.

Fat intake and breast cancer risk in an area where fat intake is low: a case-control study in Indonesia.

BACKGROUND: Associations of fat and other macronutrients with breast cancer risk are not clear in areas where fat intake is low. METHODS: We conducted a hospital-based case-control study from 1992 to 1995 in Jakarta, Indonesia. RESULTS: The study, based on 226 cases and 452 age and socioeconomic status matched controls, provided the following findings. (a) In the pre-marriage period, the greater the fat or protein consumption, the larger the risk, whereas decreasing risk with increasing carbohydrate intake was detected. The odds ratio (OR) for the highest quartile of intake relative to the lowest was 8.47 (95% CI: 4.03-17.8) for fat, 2.19 (95% CI: 1.30-3.69) for protein, and 0.16 (95% CI: 0.08-0.31) for carbohydrate. A positive association with fat and a negative one with carbohydrate were also observed for the post-marriage period, but of weaker magnitude compared to the pre-marriage period. (b) The effects of macronutrient intakes were stronger among premenopausal than among postmenopausal women. (c) Most of the associations of protein and carbohydrate were insignificant after adjustment for fat intake. CONCLUSIONS: These findings suggest that fat intake might be an important determinant of breast cancer among populations with a low fat diet in Indonesia.
