Pregnancy-induced Hypertension: What Are the Associated Factors in Rural Areas? A Study from Rural Dehradun, Uttarakhand

Abstract Background: Pregnancy-induced hypertension (PIH) is a major significant cause of adverse pregnancy outcomes – mortality and morbidities in both mother and foetus. Aims: The present study aims to determine the prevalence of PIH and its associated factors among pregnant women attending antenatal care in rural field areas of a tertiary care hospital in Uttarakhand. Patients and Methods: A cross-sectional study was conducted on pregnant women-seeking antenatal services from January 2020 to October 2020 at three sub-centres (Raiwala, Pratit Nagar and Haripur Kala) of the Primary Health Centre (Raiwala) after giving informed consent. A sample size of 113 was calculated and included in our study. A pre-tested structured schedule was used to interview the study participants after a pilot test. Blood pressure was determined using an average of three measurements, and some clinical and laboratory findings were reviewed from medical records; these were mainly the mother-child protection card. Data were presented as frequency, percentage frequencies and the results are presented with the table. Fisher’s exact statistics were calculated for the association with pregnancy-induced hypertension, and logistic regression was performed to identify independent predictors. P <0.05% was considered statistically significant. Results: The prevalence of PIH among total study participants in Dehradun District, Uttarakhand, was 6.2% (95% confidence interval [CI], 1.8%–10.6%). The majority of respondents were noted in ≤ 30 years of age group (91.15%), followed by > 30 years of age group (8.84%). In univariate regression, factors such as age, pre-term birth, abortion, pedal oedema, blurred vision, proteinuria, present history of gestational diabetes mellitus, present history of diabetes, present history of other morbidities, past history of diabetes, past history of other morbidities, i.e. surgeries, otitis media, obesity and thyroid, family history of hypertension and family history of diabetes were associated with pregnancy-induced hypertension. In multivariate logistic regression, maternal age (adjusted odds ratio AOR = 18.29, 95 CI% =2.3–141.4, P = 0.005*), pre-term birth (AOR = 61.7, 95% CI = 3.5–1071.3, P = 0.005*), (proteinuria AOR = 8, CI = 0.80–79.6, P = 0.006*), gestational diabetes (AOR = 19.9, CI = 2.9–133.06, P = 0.002*), history of other morbidities (AOR = 13.4, 95% CI; 1.7–106.5, P = 0.014*) and family history of diabetes (AOR; 8.7, 95% CI = 1.7–43.3, P = 0.008*) were found as the predictor factors for developing PIH. Conclusions: Early detection and treatment of pregnancy-induced hypertension and risk factors in pregnant women by healthcare professionals and policy-makers at the community level should be strengthened.
