Enhanced Participation in Diabetes Screening and Care After Gestational Diabetes Through Community Health Workers: Results from the Es Mejor Saber Randomized Controlled Trial.

Gestational diabetes mellitus (GDM) is a strong risk factor for type 2 diabetes mellitus, but many women with GDM do not return for postpartum diabetes screening. Interventions utilizing community health workers have demonstrated improvements in health knowledge and participation in other disease settings. The objective of this study was to therefore determine whether bilingual, bicultural community health workers (i.e., promotoras) increase participation in postpartum disease screening and referral for diabetes prevention or care in an urban, low-resource Hispanic community. Ninety-four women with GDM were recruited from the postpartum ward of a safety-net hospital and randomized equally to receive either standard-of-care alone or standard-of-care with a promotora-based intervention consisting of education, appointment reminders, and assistance navigating the healthcare system. Adherence to diabetes screening visits by 12 weeks postpartum and referral for preventive or diabetes care by 18 weeks postpartum was assessed through electronic medical record review. Compared to controls, women in the promotora group completed more diabetes screening visits (74% vs. 96%; relative risk [RR] 3.9; 95% Confidence Interval [CI] 1.1-14.1; p = 0.04). Among those who completed diabetes screening visits, women in the promotora group were also more likely to complete a subsequent referral visit for preventive or diabetes care (17% vs. 83%; RR 4.0; 95% CI 2.1-7.4; p < 0.01). A promotora-based intervention consisting of bilingual, bicultural community health workers improved diabetes screening, prevention, and treatment visits in a resource-limited community of Hispanic women with GDM.

A pilot study examining short-term changes in bone mineral density among class 3 obese users of depot-medroxyprogesterone acetate.

OBJECTIVE: To examine changes in lumbar spine-bone mineral density (LS-BMD) among normal weight (body mass index [BMI] = 18.5-24.9 kg/m(2)), Class 1-2 obese (BMI = 30-39.9 kg/m(2)), and Class 3 obese (BMI ≥ 40 kg/m(2)) women utilising depot-medroxyprogesterone acetate (DMPA). METHODS: Five normal-weight, five Class 1-2 obese, and five Class 3 obese women received subcutaneous injections of DMPA-SC at baseline and 12 weeks later. Dual Energy X-ray Absorptiometry (DEXA) scans were performed at baseline and 18 weeks after the first injection for determination of LS-BMD and analysis of fat content. Bimonthly oestradiol (E2) levels were measured by immunoassay methods for 26 weeks. RESULTS: There were no significant demographic or LS-BMD differences among the three BMI groups. Significant differences at baseline were as expected among the three groups with respect to BMI and associated parameters (mean % total body fat, absolute fat, and weight). When used as their own controls, significant changes in LS-BMD, % body fat and absolute fat determined by DEXA occurred among all three BMI strata. Class 1-2 obese and Class 3 obese women were more likely to experience E2 fluctuations, but short-term changes in LS-BMD were similar. CONCLUSIONS: DMPA-SC administration affects L-spine bone health similarly regardless of BMI status.

The use of a low-literacy version of the Medicaid sterilization consent form to assess sterilization-related knowledge in Spanish-speaking women: results from a randomized controlled trial.

OBJECTIVE: To learn whether a version of the Medicaid Sterilization Consent Form (SCF) adapted for populations of low-literacy can help Spanish-speaking women better understand the process and consequences of tubal sterilization. STUDY DESIGN: We randomly assigned Spanish-speaking women, ages 21-45 years, to review either a "standard" or "low-literacy" version of the Medicaid SCF. We assessed sterilization-related knowledge using items from the Postpartum Tubal Sterilization Knowledge questionnaire, using as the primary outcome correct identification of least four or more knowledge items and as secondary outcome participants' preferred version of the SCF. RESULTS: Overall sterilization-related knowledge was low in both groups, with 33% of women (n=100) who reviewed the standard SCF form and 42% of those who reviewed the low-literacy form (n=100) correctly identifying four or more knowledge-related items (p=.19). Regarding specific items, women in the low-literacy SCF group were more likely than those in the standard SCF group to understand the permanence of sterilization (69% versus 49%, p<.01) and the time requirement between signing the consent document and undergoing sterilization (79% versus 59%, p<.01). The groups were similar in appreciating availability of equally effective nonpermanent contraceptive options (71% versus 64%, p=.29), time from signing to expiration (33% versus 38%, p=.46), or non-binding nature of sterilization consent (55% versus 62%, p=.32). Overall, 71% of participants from both groups preferred the low-literacy form. CONCLUSION: In our patient population, characterized by low educational attainment and inadequate health literacy skills, a low-literacy SCF did not improve overall sterilization-related knowledge when compared to the standard SCF. The low-literacy version did improve understanding of the permanence of sterilization and time requirements to undergo the procedure. IMPLICATIONS: Neither form conveyed an adequate level of knowledge to this vulnerable Spanish-speaking population. Therefore, a considerable need persists for detailed education regarding availability of equally effective reversible contraceptive options, procedure-related risks, and permanence of sterilization throughout the process of informed consent.

The Effect of Depo Medroxyprogesterone Acetate (DMPA) on Cerebral Food Motivation Centers: A Pilot Study using Functional Magnetic Resonance Imaging.

OBJECTIVE: The primary objective is to examine activation of food motivation centers in the brain before and 8 weeks after depo medroxyprogesterone acetate (DMPA) administration. STUDY DESIGN: This prospective experimental pilot study examined the effects of DMPA on food motivation centers utilizing functional magnetic resonance imaging (fMRI) in eight nonobese, ovulatory subjects. fMRI blood oxygen level dependent (BOLD) signal was measured using a 3-Tesla Scanner while participants viewed images of high-calorie foods, low-calorie foods and nonfood objects. fMRI scans were performed at baseline and 8 weeks after participants received one intramuscular dose of DMPA 150 mg. fMRI data were analyzed using the FMRIB Software Library. Changes in adiposity and circulating leptin and ghrelin levels were also measured. RESULTS: There was a greater BOLD signal response to food cues in brain regions associated with food motivation (anterior cingulate gyrus, orbitofrontal cortex) 8 weeks after DMPA administration compared to baseline (z>2.3, p<.05 whole-brain analysis clustered corrected). No statistically significant change was detected in circulating leptin or ghrelin levels or fat mass 8 weeks after DMPA administration. CONCLUSION: Analysis of differences in food motivation may guide the development of interventions to prevent weight gain in DMPA users. IMPLICATIONS: These data support a neural origin as one of the mechanisms underlying weight gain in DMPA users and may guide future research examining weight gain and contraception.

Immediate post-abortion insertion of intrauterine contraceptives (IUC) in a diverse urban population.

Ethnic minority women have a higher incidence of unintended pregnancy and abortion than Caucasian women, with significant individual and social implications. Post-abortion intrauterine contraceptive (IUC) use may reduce future unintended pregnancy. This was a retrospective review of 265 women undergoing abortion at a Los Angeles County Reproductive Options Clinic. Demographic factors, reproductive history, and post-abortion contraceptive choice were evaluated and analyzed. The population was predominantly Latina (73%) and single, with a mean age of 27. Immediate post-abortion IUC insertion was chosen by 48% overall and more frequently by Latinas (55%) than by African Americans (33%) or Asians (43%) (p = 0.02). IUC use increased with age, undesired future fertility, increasing gravidity, and history of previous abortion in univariate analysis. In multivariate analysis, IUC use increased with Latina ethnicity and increasing gravidity. In a clinic serving low-income urban women in Los Angeles, post-abortal IUC uptake is highest among Latinas and those with prior pregnancies. Future research should examine reasons for and barriers to IUC uptake in diverse communities and methods to improve post-abortion IUC uptake to prevent subsequent unintended pregnancies.

Effects of progestin-only long-acting contraception on metabolic markers in obese women.

BACKGROUND: The metabolic effects of progestin-only long-acting reversible contraception [levonorgestrel-releasing intrauterine system (LNG-IUS) and etonogestrel implant (ENG-I)] have been studied in normal-weight women but not in obese [body mass index≥30kg/m(2)] women. STUDY DESIGN: A nonrandomized open-label prospective trial of healthy obese, reproductive-age women desiring to use long-acting reversible contraception (LARC) or nonhormonal contraception (NHC). At baseline, 3 months and 6 months, homeostasis model assessment insulin resistant (HOMA-IR) score, insulin sensitivity (HOMA-%S) and ß-cell function (HOMA-%B) were calculated based on fasting insulin and glucose values. In addition, components of metabolic syndrome [fasting glucose (FG), high density lipoprotein cholesterol and triglycerides, systolic and diastolic blood pressure, abdominal circumference] were measured. Twenty-four subjects total (8 in each arm) were needed to detect a 1.0 difference in HOMA-IR with 80% power and a two-sided alpha of 0.05. RESULTS: We present data on eight NHC, eight ENG-I and nine levonorgestrel intrauterine system (LNG-IUS) users. FG increased, and insulin sensitivity decreased over time among ENG-I users to a greater extent than among LNG-IUS users when compared to women using a nonhormonal method [FG change over 6 months=9.4mg/dL, 4.6mg/dL and -2.1mg/dL, respectively; p=.01); (HOMA-%S change over 6 months=-29.9%, -14.8% and 19.3%, respectively; p=.02)], while ß-cell function and insulin resistance did not change significantly (p>.05). CONCLUSION: While changes in FG and insulin sensitivity were seen in the present study among obese progestin-only contraceptive users, either progestin-only LARC method may be safely used clinically.

Effect of subcutaneous depot-medroxyprogesterone acetate (DMPA-SC) on serum androgen markers in normal-weight, obese, and extremely obese women.

BACKGROUND: The effects of subcutaneous depo-medroxyprogesterone acetate (DMPA-SC) injection on androgenic markers in obese women have not previously been studied. STUDY DESIGN: Five normal-weight [body mass index (BMI)=18.5-24.9 kg/m²], five obese (BMI=30-39.9 kg/m²) and five extremely obese (BMI≥40 kg/m²) women were recruited for this prospective experimental study in which 104 mg DMPA-SC was administered at baseline and 12 weeks later. Serum levels of total testosterone (T), androstenedione (A), dehydroepiandrosterone sulfate (DHEAS), 3α-androstanediol glucuronide and sex hormone-binding globulin (SHBG) were quantified by immunoassay methods at baseline and at 13 and 26 weeks following the first injection; free T was calculated. RESULTS: At baseline, obese women had lower levels of A and SHBG and higher total and free T levels than normal-weight women. There were a statistically significant decrease in the levels from baseline to week 26 among all three BMI classes for A, total T and SHBG (p≤.03) and an increase from baseline to week 26 in weight (p=.02). In addition, there was a statistically significant decrease in DHEAS from baseline to week 13 among all three BMI classes (p=.01), which was not sustained at week 26 (p>.1). Overall, the three groups responded similarly to all changes at week 13, and there were no statistically significant differences between groups at any time point (p≥.06). CONCLUSION: DMPA-SC use in normal-weight, obese and extremely obese women can decrease serum androgen markers.

Deterioration in cardiometabolic risk markers in obese women during depot medroxyprogesterone acetate use.

BACKGROUND: Highly effective contraception is essential in obese women, but it should not increase their risk of developing or worsening obesity-related cardiometabolic illness. The purpose of this 18-week prospective experimental study was to compare the impact of subcutaneous depot medroxyprogesterone acetate (DMPA-SC) on cardiometabolic markers in obese and normal-weight women. METHODS: Normal-weight [body mass index (BMI) 18.5-24.9 kg/m(2)] and obese (BMI≥30 kg/m(2)) women received injections of 104 mg DMPA-SC at baseline and 12 weeks later. Markers of cardiometabolic risk measured at baseline and 18 weeks after the first injection included body morphometry, fasting blood tests, and oral and frequently sampled intravenous glucose tolerance tests (FSIGT). RESULTS: At baseline, median gravidity, BMI, abdominal circumference, and acute insulin response to intravenous glucose were higher and high-density lipoprotein (HDL) cholesterol and insulin sensitivity (S(I) from FSIGTs) were lower in the 10 obese participants than the five normal-weight women (p≤.05 for each). While there was no significant difference between median baseline and follow-up values among normal-weight women, the difference between median baseline and follow-up among the obese cohort was significantly higher for BMI and lower for HDL cholesterol and insulin sensitivity (S(I)) (p≤.05 for each). The absolute changes for routinely measured clinical laboratory values of metabolic decline were no different among the normal-weight vs. obese women. The difference in absolute change in ß-cell compensation for insulin resistance [disposition index (DI)] was significant between the two groups at follow-up, with the normal-weight group experiencing an increase in DI while the obese group experienced a decline in DI (188.5 vs. -286, p=.04). CONCLUSIONS: Obese women have an increased baseline cardiometabolic risk when compared with normal-weight women at baseline. There was a significantly greater decline in ß-cell compensation for insulin resistance in obese women on DMPA. Our data suggest potential deleterious effects of DMPA on glucose regulation in obese women. Further studies should elucidate the long-term cardiometabolic consequences of DMPA use in obese women.

The incidence of depression by fertility status in overweight and obese Latina women.

The link between depression, obesity, and fertility status is poorly understood among Latina women. The Patient Health Questionnaire 9 (PHQ-9) is routinely administered in the Diabetes and Obesity in Reproductive Age women Clinic. We describe median PHQ-9 score and PHQ-9 score ≥10 [indicative of Major Depressive Disorder (MDD)] by fertility status. Of the 76 eligible new patients seen between June 2008 and 2009, 18.4% (n = 14) had PHQ-9 scores indicative of MDD. Infertile women had marginally significantly higher PHQ-9 scores than non-infertile women (p = 0.08). 26.5% of infertile women and 12.2% of non-infertile women had a PHQ-9 score indicative of MDD (p = 0.14). Number of previous births was inversely correlated with PHQ-9 score (R = -0.34, p = 0.002), those with no previous births had higher PHQ-9 scores (p = 0.001) and were more likely to have a PHQ-9 score indicative of MDD than those with previous births (28.6 vs. 9.8%, p = 0.04). Among non-infertile women, postpartum women had significantly lower PHQ-9 scores than non-postpartum women (p = 0.002). 4.6% of postpartum women and 21.1% of non-postpartum women had a PHQ-9 indicative of MDD (p = 0.19). Further investigation is needed to determine if reproductive success is protective against MDD among overweight and obese urban Latinas. Overall, depression is common among overweight and obese reproductive-age Latinas and thus routine screening is recommended.

Determinants of intrauterine contraception provision among US family physicians: a national survey of knowledge, attitudes and practice.

BACKGROUND: Poor contraception adherence contributes to unintended pregnancy. Intrauterine contraception (IUC) is user-independent thus adherence is not an issue, yet few US women use IUC. We compared family physicians (FPs) who do and do not insert IUC in order to ascertain determinants of inserting IUC. STUDY DESIGN: We surveyed 3500 US FPs. The primary outcome variable was whether a physician inserts IUC in their current clinical practice. We also sought to describe their clinical practice with IUC insertions. RESULTS: FPs who insert IUC had better knowledge about IUC (adjusted OR 1.85, 95% CI 1.32-2.60), more comfort discussing IUC (adjusted OR 2.35, 95% CI 1.30-4.27), and were more likely to believe their patients are receptive to discussing IUC (adjusted OR 2.96, 95% CI 2.03-4.32). The more IUC inserted during residency, the more likely to insert currently (adjusted OR 1.44, 95% CI 1.12-1.84). Only 24% of respondents inserted IUC in the prior 12 months. CONCLUSIONS: US FPs have training and knowledge gaps, as well as attitudes, that result in missed opportunities to discuss and provide IUC for all eligible patients.

Follicular development and ovulation in extremely obese women receiving depo-medroxyprogesterone acetate subcutaneously.

BACKGROUND: Subcutaneous depo-medroxyprogesterone acetate (DMPA-SC) has not been studied in the extremely obese population (BMI >or=40 kg/m(2)). The purpose of this 26-week prospective experimental study was to determine incidence of ovulation and follicular development among women with Class 1, 2 and 3 obesity after receiving DMPA-SC. METHODS: Five normal-weight, five Class 1-2 obese, and five Class 3 obese women received subcutaneous injections of 104 mg DMPA-SC at baseline and 12 weeks later. Weekly progesterone levels, bimonthly estradiol (E(2)), and monthly medroxyprogesterone acetate (MPA) levels were measured by immunoassay methods for a total of 26 weeks in each subject. RESULTS: Ovulation did not occur in any subject more than 1 week after the first injection. There was large intersubject and intrasubject variability in E(2) levels, and fluctuating E(2) levels were more frequent among obese women than normal-weight women. Median MPA levels remained above the level needed to prevent ovulation but, compared with normal-weight subjects, were lower among Class 1-2 obese and lowest among Class 3 obese subjects. CONCLUSION: Fluctuating E(2) levels reflective of follicular development occurred more often among Class 1, 2 and 3 obese women than normal-weight women after DMPA-SC injections. Median MPA levels were consistently lowest among Class 3 obese women but remained above the level needed to inhibit ovulation. Further studies should more fully address the pharmacokinetics of DMPA-SC in extremely obese women.
