One of the most important predictors of preterm births (PTBs) or low-birth-weight births (LBWBs) is whether a mother has had a history of these birth outcomes. This study examined how different characterizations of birth history (e.g., any previous incidence of PTBs or LBWBs, immediate previous birth that was preterm or of low birth weight, and number of previous PTBs or LBWBs) were associated with PTBs or LBWBs. Based on birth records (n = 98,776) reported to the vital statistics electronic registration system in Nebraska from 2005 to 2014, mothers with a history of PTBs or LBWBs were more likely to have recurrences of these outcomes than those who did not have any history of PTBs or LBWBs. The adjusted odds ratios for recurrent PTBs ranged from 2.82 (95% CI: 2.62, 3.04) to 5.54 (95% CI: 4.67, 6.57) depending on how previous incidence of PTBs or LBWBs were characterized. The corresponding adjusted odds ratio for LBWBs ranged from 1.58 (95% CI: 1.43, 1.74) to 6.75 (95% CI: 4.96, 9.17). Relative to other measures used to characterize birth history, the use of number of previous PTBs or LBWBs allows for identifying mothers most vulnerable to recurrences of these birth outcomes. To help identify mothers at risk for future PTBs or LBWBs, it is beneficial to develop state-wide surveillance of reoccurrences for adverse birth outcomes which is feasible by integrating all separated birth records for the same mother using vital statistics data.
Human papillomavirus (HPV) vaccination is now available for adults aged 27–45 as a shared clinical decision. Health literacy skills (i.e., accessing, understanding, appraising, applying information) may facilitate vaccine decision-making for adults with a provider recommendation. This study assessed associations between health literacy skills and willingness to get a provider-recommended HPV vaccine among newly eligible US adults. In 2020, US participants (51% women), aged 27–45 years, were surveyed online ( n = 691). The outcome was willingness (willing/not willing) to get the HPV vaccine with provider recommendation. Measures were adapted from Sørensen’s multidimensional European Health Literacy Scale, which assesses health literacy among four domains (i.e., access, understanding, appraisal, application). Adjusted odds ratios were calculated for the outcome and each health literacy domain, adjusting for personal health determinants (e.g., age, sex). The sample consisted of primarily non-Hispanic (91.2%), White (74.4%), and married (60.7%) adults. Approximately 65% of participants were willing to get a provider-recommended HPV vaccine. Higher willingness to vaccinate with provider recommendation was significantly associated with increased HPV knowledge (understanding; aOR = 1.13, 95% CI 1.04, 1.24), ability to understand HPV information (understanding; aOR = 1.96, 95% CI 1.09, 3.52), increased perceived vulnerability to HPV-related cancer (appraising; aOR = 3.22, 95% CI 1.83, 5.69), and the need for more information on vaccine safety to seek vaccination (applying; aOR = 3.25; 95% CI 2.05, 5.16). Utilizing a multidimensional health literacy framework to evaluate facilitators to HPV vaccination uptake among adults aged 27–45 can help guide future interventions by targeting accurate, easy-to-understand HPV information that connects vaccination efficacy to reduction in HPV cancer risk.
Background Women experiencing homelessness are at higher risk of unintended pregnancy than women stably housed. The way women perceive their susceptibility to pregnancy may contribute to effective contraceptive use. This study aimed to explore how women experiencing homelessness perceive their susceptibility to pregnancy with and without contraception from a qualitative, emic perspective. Methods Semi-structured interviews (n = 19) were conducted from December 2019 to October 2020 among English-speaking, pregnancy-capable (i.e. not sterilised) women, aged 18–45 years, experiencing homelessness. Interview questions included perceived susceptibility to pregnancy with and without contraception, attitudes toward pregnancy, and pregnancy intention. Interviews were audio-transcribed and coded to consensus using a seven-step coding process. Themes were identified via thematic and framework analysis, stratifying participants by pregnancy desire in the next year: yes (n = 4), no (n = 9), or don’t know (n = 6). Results Seventeen women reported inconsistent or no contraceptive use. Some women found their risk of pregnancy was equal with and without contraception based on perceptions of specific contraception efficacy (e.g. condoms vs pills); fertility and fecundity concerns; and high abstinence self-efficacy themes. In stratified analysis, women who desired pregnancy or were uncertain of pregnancy desire in the next year reported similar perceived susceptibility with and without contraception, compared with women not desiring pregnancy in the next year. Conclusions Given the need to have higher susceptibility to pregnancy without contraceptive use for consistent contraception uptake, findings may explain the lack of contraceptive behaviours and contraception preferences related to pregnancy desire.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
