“…Indeed, in our larger randomized controlled trial, women who received our comprehensive daily text message intervention (which entailed educational information and behavioral reminders) were 44% more likely to continue OCs at 6 months compared with the control group. 11 Unfortunately, we had limited power to further examine the effect of each OC knowledge dimension, as well the effect of ''dosage'' of intervention content for each dimension, on OC continuation and pregnancy rates.…”

“…Potential covariates, including sociodemographic and reproductive correlates we had previously shown to be associated with OC knowledge and continuation, were considered for inclusion in regression models if their p-value in bivariate tests was £ 0.25. 11,12 We present final reduced multivariable models in which we retained only those covariates that were associated with OC knowledge or continuation at p < 0.05. For variables that appeared to be collinear (e.g., age and grade of education), we retained those variables with the strongest effect.…”

“…11 We described the sample and reported on the main text message intervention effects on OC continuation and OC knowledge elsewhere. 11,12 In brief, young women presenting to an urban family planning health center requesting OCs were informed of the study and asked to participate. Women eligible for inclusion were (1) aged 13-25 years, (2) currently sexually active, (3) owners of a cell phone with text messaging capabilities, and (4) specifically requesting OCs.…”

Background: Using a multidimensional approach, we assessed young women's knowledge of oral contraceptives (OC) and its influence on OC continuation rates. Methods: We used data from 659 women aged 13-25 years participating in a randomized controlled trial of an educational text message OC continuation intervention. Women received 6 months of daily text messages or routine care. At baseline and 6 months, we administered a comprehensive 41-item questionnaire measuring knowledge of OC's mechanism, effectiveness, use, side effects, risks, and benefits. We ascertained OC continuation status and reasons for discontinuation at 6 months. We analyzed relationships between OC knowledge and continuation with multivariable logistic regression. Results: Young women scored, on average, 22.8 out of 41 points on the OC knowledge assessment at baseline and 24.7 points at 6 months. The 6-month OC continuation rate was 59%. OC continuers had > 2-points-higher OC knowledge scores at 6 months than discontinuers ( p < 0.001). Those who reported discontinuing their OCs for side effects and forgetfulness scored > 2 points lower than women who discontinued for other reasons ( p-values < 0.001). In multivariable regression models, each correct response on the baseline and 6-month knowledge assessments was associated with a 4% and 6% increased odds of OC continuation, respectively. Six-month OC knowledge scores were negatively associated with OC discontinuation due to side effects (odds ratio [OR] 0.94) and forgetfulness (OR 0.88). Conclusions: OC knowledge, which was low among young women in our study, was associated with OC continuation and common reasons for discontinuation. Continued efforts to characterize relationships between OC knowledge and behavior and to test the effectiveness of different components of interventions aimed at increasing knowledge, addressing side effects, and improving use of OCs are warranted.

“…30 Castaño et al found that daily text-message reminders that included an educational message significantly decreased the proportion of OCP users who experienced an extended 7-day gap in use during the study. 31 Conversely, using electronic monitoring devices to record adherence, Hou et al found no difference in adherence between those receiving daily text reminders (minus the educational component) and the control group. 32 The majority of participants receiving reminders found them to be acceptable and useful.…”

Oral contraceptive pills (OCPs) remain the most commonly used reversible birth control method. Failure to adhere to daily pill taking and gaps in use are common and contribute to the risk of unintended pregnancy among OCP users. OCP compliance is influenced by a complex interplay of cognitive, behavioral, logistic, clinical, and social factors. This review outlines the evidence base for strategies that have been studied for their impact on OCP compliance.

“…This is also the age group that often selects an OC as their form of contraception (39) . Unfortunately, OC discontinuation is high (55)(56)(57) , often occurs without consulting a physician (45) and leaves women at risk for an unintended pregnancy. Therefore, attaining adequate folate stores in this population is very important.…”

Objective: To assess the folate status of US women in a study of a folate-fortified oral contraceptive (OC) using the Short Folate Food Frequency Questionnaire and plasma and red blood cell (RBC) folate samples. Design: Sub-analysis from a multi-centre, randomised, double-blind, controlled contraceptive trial with assessments at baseline and 6 months. We calculated dietary folate equivalents (DFE) consumed and the proportion of participants meeting folate adequacy benchmarks. Setting: Eight centres in the USA. Subjects: Healthy women aged 18-40 years requesting contraception with no contraindications for OC use. Results: Overall, 385 participants were randomised to either a novel folatefortified OC or a marketed OC. The 262 (68 %) participants compliant with the protocol were included in the analysis set. Baseline daily DFE consumption was 529?8 (SD 342?1) mg and similar in both groups. At follow-up, the fortified OC group had higher intake than the conventional OC group (1225?9 (SD 346?2) mg compared with 500?6 (SD 361?2) mg). Mean plasma folate level increased from 44?5 (SD 17?2) to 55?8 (SD 21?1) nmol/l. Mean RBC folate level increased from 996?7 (SD 369?8) to 1311?9 (SD 436?0) nmol/l. The proportion meeting selected folate adequacy benchmarks increased in the fortified OC group (P , 0?001). Conclusions: Lack of adequate folate intake in reproductive-aged women from dietary sources or supplements alone suggests the need for novel approaches. Use of folate-fortified OC ensures adequate folate levels and meeting of folate benchmarks.
