Objective Premarital sexual practice during adolescence time may lead to different sexual and reproductive health problems including HIV/AIDS. This study was aimed to assess the prevalence of premarital sexual practice and associated factors among adolescents living in the refugee camps in Tigray, northern Ethiopia. Result The prevalence of premarital sexual practice was 47.6% [95% CI (43.3%, 51.9%)]. The age (mean ± SD) of the study participants was 17.4 ± 2.71 (15–24 years) and 68.8% of them were males. Being in the age group 14–19 years [AOR = 4.50, 95% CI (2.29–8.84)] or 20–24 years [AOR = 9.76, CI (4.58–20.82)], living with friends [AOR = 5.24, 95% CI (2.28–12.05)] or alone [AOR = 5.72, 95% CI (2.69–12.19)], being in primary school [AOR = 6.93, 95% CI (3.08–15.57)] or college [AOR = 4.33, CI (1.44–13.02)], getting pocket money [AOR = 4.14, 95% CI (2.31–7.41)], parents being either divorced [AOR = 5.11, 95% CI (2.42–10.80)] or widowed [AOR = 3.52, 95% CI (1.69–7.33)], alcohol consumption [AOR = 1.99, 95% CI (1.20–3.38)] were independent predictors of premarital sexual practice among the adolescents.

Background Worldwide cervical cancer is the third most common malignancy in women. It usually arises from the cervical area which is susceptible to Human Papilloma virus induced malignancy changes. In low-resource setting visual inspection with acetic acid (VIA) is an alternative sensitive cervical screening method. Therefore the aim of this study was to assess the magnitude and associated factors of VIA positive test results for Cervical Cancer screening among Eritrean refugee women aged 25–49 years in northern Ethiopia refugee camps. Methods A community based cross-sectional study was conducted among 412 Eritrean refugee women aged 25–49 years from august 10 to September 25, 2018. Study subjects were selected by simple random sampling method. Data were collected using pretested structured questioner through Face-to-face interview and cervical examination. Data were coded and entered to Epi info software version 7 and then exported to Statistical package for Social Science (SPSS) version 21 for analysis. Bivariable and multivariable logistic regression analysis was made to test the association between the independent variables and the outcome variable. P-value of less than 0.05 with 95% CI was considered to declare statistical significance. Result In this study the magnitude of VIA positive precancerous cervical lesions was 9% (95% CI: 6.3–11.8%). Previous history of sexually transmitted infections (STI) [AOR (95%CI) = 2.84(1.07–7.53)] and presence of STI during cervical examination [AOR (95%CI) =3.97(1.75–9.00)] were found significantly associated with VIA positive precancerous cervical lesions. Conclusions In this study the magnitude of VIA positive precancerous cervical lesions was high. Previous history of sexually transmitted infections (STI) and presence of STI during cervical examination were found associated with VIA positive precancerous cervical lesions. Efforts such as early screening for sexually transmitted disease shall be done to prevent precancerous cervical lesions.
