Weight change among women using intramuscular depot medroxyprogesterone acetate, a copper intrauterine device, or a levonorgestrel implant for contraception: Findings from a randomised, multicentre, open-label trial. EClinicalMedicine 2021; 34:100800. [PMID: 33898953 PMCID: PMC8056402 DOI: 10.1016/j.eclinm.2021.100800] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 02/26/2021] [Accepted: 03/02/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND There is limited evidence on the impact of the use of progestin-only hormonal contraception (POC) on weight change. We conducted a secondary analysis of prospective weight change among women enrolled in the Evidence for Contraceptive options and HIV Outcomes (ECHO) trial. METHODS The ECHO trial was conducted at 12 sites in eSwatini, Kenya, South Africa and Zambia between December 2015 and October 2018. HIV negative, women aged 16-35 years, desiring contraception, were randomised (1:1:1) to either 3-monthly intramuscular depot medroxyprogesterone acetate (DMPA-IM), levonorgestrel (LNG) implant or copper intrauterine device (IUD). Follow-up was up to 18 months. Weight (kg) was measured at baseline and study exit. Analysis was performed as intention to treat (ITT) and time on continuous contraceptive use. The primary outcome of this secondary analysis is weight change from study enrolment to the final visit at study month 12-18. The ECHO trial is registered with ClinicalTrials.gov, NCT02550067. FINDINGS 7829 women were randomly assigned to DMPA-IM (n = 2609), copper IUD (n = 2607) or LNG implant (n = 2613). The ITT population included 7014 women 2293 DMPA-IM group, 2372 copper IUD group and 2349 LNG group) who were not lost to follow-up, pregnant on study, or missing weight data. The mean weight increased in all groups but was significantly different in magnitude: 3.5 kg (SD = 6.3), 2.4 kg (SD = 5.9) and 1.5 kg (SD = 5.7) in the DMPA-IM, LNG implant and copper IUD groups, respectively. Comparative differences between groups were (2.02 kg (95% CI, 1.68, 2.36, p < 0.001) for DMPA-IM versus copper IUD, 0.87 kg (0.53,1.20 p < 0.001) for LNG implant compared to copper IUD and 1.16 kg (0.82, 1.50, p < 0.001) for DMPA-IM compared with LNG implant. Results for continuous contraceptive use were similar. INTERPRETATION We found differences in weight gain between POC users compared to the non-hormonal copper IUD group over 12-18 months of use. Women using POCs should be counselled about this potential side effect when choosing a contraceptive method.

Abstract
BACKGROUND The major types of hormonal contraception used currently in Ethiopia are progestogen-only. This study aimed to assess the differences in anthropometry indices, blood pressure, and lipid profile among women using progestin-only contraceptives in selected health facilities of Jimma town, southwest Ethiopia. METHODS A facility-based comparative cross-sectional study was conducted among women of reproductive age using Depo-medroxyprogesterone acetate (DMPA) and implant in selected health facilities from April 11 to May 11, 2019. A total of 146 women (45 DMPA and 51 implant users and 50 non-users) were selected randomly for inclusion in the study. One-way analysis of variance was used to examine variations in health outcomes while Bonferroni post-hoc tests were conducted to determine significance of variations between multiple outcomes. RESULTS There was a statistically significant difference in the mean Body Mass Index (p = 0.045), Hip-to-waist ratio (p = 0.012), systolic blood pressure (p = 0.027), diastolic blood pressure (DBP) (p = 0.017), total cholesterol (TC) (p = 0.005), low-density lipoprotein (p = 0.023) and triacylglycerol (TAG) (p = 0.000) between women using progestin-only contraceptives and non-users. DMPA users had higher TC (p = 0.024) than non-users. Results from Pearson correlation analysis showed that DBP of DMPA users was higher with longer duration of use. CONCLUSION The findings suggest the need for family planning service providers to undertake appropriate client profiling before recommending a particular method to women seeking the services in order to minimize adverse health risks, especially for those who may have pre-existing conditions.

Abstract
Overweight stands out as a growing health problem in the population, resulting in individual and societal burdens. This study aimed to identify the association between reproductive factors and overweight in women of reproductive age attended by a Primary Health Care Unit (UAPS).This is a cross-sectional study with home capitation and data collection in two PHC Units, in the city of Juiz de Fora (MG), Brazil, in women aged 20 to 59 years, whose outcome was the overweight measured by the Body Mass Index. The prevalence of overweight was 61.0% among the 2,018 women included in the analysis. In the multivariate analysis, overweight was associated with the variables age at menarche before 12 years of age, having children, age greater than or equal to 30years, and hypertension. The prevalence of overweight in women who had menarche before 12 years of age was 12.4% higher than those who had menarche aged 12 years or more, and the prevalence of overweight in women who had children was 58.2% higher than those who never had any. There was a high prevalence of overweight in the adult female population, emphasizing the influence of reproductive factors.

Abstract
OBJECTIVES Depo-Provera is an injectable contraceptive method containing medroxyprogesterone acetate. It has some adverse effects like changes in menstrual pattern, loss in bone mineral density and risk of weight gain. Therefore, this study is aimed at to investigate the effects of Depo-Provera on body weight and blood pressure among Ethiopian women. Institution based cross-sectional study design was conducted from January 2017 to April 2017. Data were analyzed using SPSS version 21 software. Paired t test, independent t-test and ANOVA were used to evaluate the presence of mean difference and relationship between changes in variables and duration of use of Depo-Provera. P-value ≤ 0.05 were considered as statistically significant. RESULTS The mean weight and body mass index (BMI) of Depo-Provera users were increased significantly (p = 0.02 for mean body weight and p = 0.019, for body mass index). There was no significant difference in mean arterial blood pressure (MAP) of Depo-Provera users compared to controls or their respective pretreatment value (p-value = 0.85 for Depo-Provera users and 0.67 for non-users). The finding of this study revealed that there is an increased weight gain and BMI among Depo-Provera users compared to non-users, which really requires attention of health professionals and other stake holders.

Abstract
OBJECTIVES Chronic hypertension in pregnancy is an important cause of maternal and neonatal morbidity and mortality. The aim of this study was to determine the effect of severity of chronic hypertension in pregnancy on maternal and perinatal outcome in an Indonesian population. STUDY DESIGN This study was performed in Dr Soetomo General Hospital, a tertiary center in East - Java, Indonesia over the period of 2013-2017. Chronic hypertension (CH) was divided using JNC VII criteria, as stage 1 (Blood pressure ≥140/90 mmHg) and Stage 2 (BP > 160/110 mmHg) hypertension. MAIN OUTCOME MEASURES The primary outcomes were maternal and perinatal outcome. Data was statistically analyzed using Chi-square, Fischer exact test, and Mann-Whitney test (program: SPSS ®23). RESULTS Over these 5 years, 352 patients were diagnosed with CH. The stage 2 of CH was associated with worse maternal outcome: maternal death (5.6% vs 0.8%; p = 0.016), laboratory values of urinary protein +3 (67% vs 21,5%, p = 0.001) and +4 (12.3% vs 0.4%, p = 0.001), LDH > 600 IU/L (11.3% vs 5.3%, p = 0.04), ALT > 70 IU/L (11.3% vs 4.1%, p = 0.01), AST > 70 IU/L (12.3% vs 5.3%, p = 0.02), BUN > 25 mg/dL (27.4% vs 8.1%, p = 0.001), SK > 1.1 mg/dL (29.2% vs 6.5%, p = 0.001) and Albumin <3 g/dL (65.1% vs 10.2%, p = 0.001), need for ICU admission (76.4% vs 36.6%, p = 0.001), mechanical ventilation (48.1% vs 21.1%, p = 0.001), and occurrence of complications (72.6% vs 57.7%, p = 0.006). Stage 2 CH in pregnancy was associated with an increased risk of maternal death (OR: 7.22; 95% CI: 1.43-36.36; p = 0,016). Stage 2 CH was also associated with worse perinatal outcome, in terms of lower birth weight (1635 ± 863.27 vs 2063.74 ± 935.43, p = 0.001), lower Apgar score (p = 0.001), and number of intra uterine complications such as: IUGR, stillbirth, and placental abruption (27.4% vs 11.8%, p = 0.001). CONCLUSIONS Stage 2 CH in pregnancy is associated with worse maternal and perinatal outcomes compared with stage 1. Intervention to prevent disease progression to stage 2 before pregnancy may improve maternal and perinatal outcomes during pregnancy.

Abstract
PURPOSE The aim of the study was to evaluate thyroid function profile as a possible factor influencing weight and body composition variation in new users of depot medroxyprogesterone acetate (DMPA). MATERIALS AND METHODS A prospective, non-randomised, comparative study was conducted at the University of Campinas, Brazil. Women aged 18-40 years with a body mass index (BMI) less than 30 kg/m2, normal oral glucose tolerance test, no known diseases, and using no medication, who opted to use DMPA were paired by age (±1 year) and BMI (±1 kg/m2) with women initiating copper intrauterine device (IUD) use. The main outcome measures were thyroid function profile, weight, and body composition, as measured by dual-energy X-ray absorptiometry. We used repeated measures ANOVA to perform comparisons between times and groups. RESULTS We evaluated 28 DMPA users and 24 IUD users who completed the 12-month follow-up. We observed that FT4 levels were higher at 12 months (compared to baseline) in the DMPA group (p < .0001) and that FT4/FT3 ratio had increased in both groups. Additionally, at 12 months, total body mass had increased around 2 kg and lean mass increased in the DMPA group compared to the IUD group; there was also an increase in weight, BMI, total body mass, and fat mass when compared to baseline. CONCLUSIONS No changes in thyroid function occurred that could explain the weight increase observed in DMPA users.

Abstract
The intrauterine devices (IUDs) and the subdermal implant, collectively known as long-acting reversible contraceptives (LARC), along with the Depo-Provera shot, represent highly efficacious methods of birth control for all reproductive-age women, including adolescents. They are also safe, private, and convenient, and can be used for their noncontraceptive benefits. Additionally, LARC and Depo-Provera represent methods of contraception that do not contain estrogen and may be safely used in young women who have contraindications to estrogen-containing medications. The LARC methods have traditionally been underused by adolescents due to lack of knowledge and misperceptions about safety and effects on future fertility. However, studies have found that when barriers to the use of LARC are removed, adolescents have increasingly chosen the IUD and implant for birth control and most continue to use these methods with satisfaction. This chapter will provide an overview of IUDs, the subdermal implant and Depo-Provera, address barriers to care for adolescents, efficacy, continuation rates, common side effects and reasons for discontinuation, contraindications, and noncontraceptive benefits.

Abstract
BACKGROUND Obesity is caused by an imbalance between energy intake, i.e. eating and energy expenditure (EE). Severe obesity is more prevalent in women than men worldwide, and obesity pathophysiology and the resultant obesity-related disease risks differ in women and men. The underlying mechanisms are largely unknown. Pre-clinical and clinical research indicate that ovarian hormones may play a major role. OBJECTIVE AND RATIONALE We systematically reviewed the clinical and pre-clinical literature on the effects of ovarian hormones on the physiology of adipose tissue (AT) and the regulation of AT mass by energy intake and EE. SEARCH METHODS Articles in English indexed in PubMed through January 2016 were searched using keywords related to: (i) reproductive hormones, (ii) weight regulation and (iii) central nervous system. We sought to identify emerging research foci with clinical translational potential rather than to provide a comprehensive review. OUTCOMES We find that estrogens play a leading role in the causes and consequences of female obesity. With respect to adiposity, estrogens synergize with AT genes to increase gluteofemoral subcutaneous AT mass and decrease central AT mass in reproductive-age women, which leads to protective cardiometabolic effects. Loss of estrogens after menopause, independent of aging, increases total AT mass and decreases lean body mass, so that there is little net effect on body weight. Menopause also partially reverses women's protective AT distribution. These effects can be counteracted by estrogen treatment. With respect to eating, increasing estrogen levels progressively decrease eating during the follicular and peri-ovulatory phases of the menstrual cycle. Progestin levels are associated with eating during the luteal phase, but there does not appear to be a causal relationship. Progestins may increase binge eating and eating stimulated by negative emotional states during the luteal phase. Pre-clinical research indicates that one mechanism for the pre-ovulatory decrease in eating is a central action of estrogens to increase the satiating potency of the gastrointestinal hormone cholecystokinin. Another mechanism involves a decrease in the preference for sweet foods during the follicular phase. Genetic defects in brain α-melanocycte-stimulating hormone-melanocortin receptor (melanocortin 4 receptor, MC4R) signaling lead to a syndrome of overeating and obesity that is particularly pronounced in women and in female animals. The syndrome appears around puberty in mice with genetic deletions of MC4R, suggesting a role of ovarian hormones. Emerging functional brain-imaging data indicates that fluctuations in ovarian hormones affect eating by influencing striatal dopaminergic processing of flavor hedonics and lateral prefrontal cortex processing of cognitive inhibitory controls of eating. There is a dearth of research on the neuroendocrine control of eating after menopause. There is also comparatively little research on the effects of ovarian hormones on EE, although changes in ovarian hormone levels during the menstrual cycle do affect resting EE. WIDER IMPLICATIONS The markedly greater obesity burden in women makes understanding the diverse effects of ovarian hormones on eating, EE and body adiposity urgent research challenges. A variety of research modalities can be used to investigate these effects in women, and most of the mechanisms reviewed are accessible in animal models. Therefore, human and translational research on the roles of ovarian hormones in women's obesity and its causes should be intensified to gain further mechanistic insights that may ultimately be translated into novel anti-obesity therapies and thereby improve women's health.

Abstract
BACKGROUND Progestin-only contraceptives (POCs) are appropriate for many women who cannot or should not take estrogen. POCs include injectables, intrauterine contraception, implants, and oral contraceptives. Many POCs are long-acting, cost-effective methods of preventing pregnancy. However, concern about weight gain can deter the initiation of contraceptives and cause early discontinuation among users. OBJECTIVES The primary objective was to evaluate the association between progestin-only contraceptive use and changes in body weight. SEARCH METHODS Until 4 August 2016, we searched MEDLINE, CENTRAL, POPLINE, LILACS, ClinicalTrials.gov, and ICTRP. For the initial review, we contacted investigators to identify other trials. SELECTION CRITERIA We considered comparative studies that examined a POC versus another contraceptive method or no contraceptive. The primary outcome was mean change in body weight or mean change in body composition. We also considered the dichotomous outcome of loss or gain of a specified amount of weight. DATA COLLECTION AND ANALYSIS Two authors extracted the data. Non-randomized studies (NRS) need to control for confounding factors. We used adjusted measures for the primary effects in NRS or the results of matched analysis from paired samples. If the report did not provide adjusted measures for the primary analysis, we used unadjusted outcomes. For RCTs and NRS without adjusted measures, we computed the mean difference (MD) with 95% confidence interval (CI) for continuous variables. For dichotomous outcomes, we calculated the Mantel-Haenszel odds ratio (OR) with 95% CI. MAIN RESULTS We found 22 eligible studies that included a total of 11,450 women. With 6 NRS added to this update, the review includes 17 NRS and 5 RCTs. By contraceptive method, the review has 16 studies of depot medroxyprogesterone acetate (DMPA), 4 of levonorgestrel-releasing intrauterine contraception (LNG-IUC), 5 for implants, and 2 for progestin-only pills.Comparison groups did not differ significantly for weight change or other body composition measure in 15 studies. Five studies with moderate or low quality evidence showed differences between study arms. Two studies of a six-rod implant also indicated some differences, but the evidence was low quality.Three studies showed differences for DMPA users compared with women not using a hormonal method. In a retrospective study, weight gain (kg) was greater for DMPA versus copper (Cu) IUC in years one (MD 2.28, 95% CI 1.79 to 2.77), two (MD 2.71, 95% CI 2.12 to 3.30), and three (MD 3.17, 95% CI 2.51 to 3.83). A prospective study showed adolescents using DMPA had a greater increase in body fat (%) compared with a group not using a hormonal method (MD 11.00, 95% CI 2.64 to 19.36). The DMPA group also had a greater decrease in lean body mass (%) (MD -4.00, 95% CI -6.93 to -1.07). A more recent retrospective study reported greater mean increases with use of DMPA versus Cu IUC for weight (kg) at years 1 (1.3 vs 0.2), 4 (3.5 vs 1.9), and 10 (6.6 vs 4.9).Two studies reported a greater mean increase in body fat mass (%) for POC users versus women not using a hormonal method. The method was LNG-IUC in two studies (reported means 2.5 versus -1.3; P = 0.029); (MD 1.60, 95% CI 0.45 to 2.75). One also studied a desogestrel-containing pill (MD 3.30, 95% CI 2.08 to 4.52). Both studies showed a greater decrease in lean body mass among POC users. AUTHORS' CONCLUSIONS We considered the overall quality of evidence to be low; more than half of the studies had low quality evidence. The main reasons for downgrading were lack of randomizations (NRS) and high loss to follow-up or early discontinuation.These 22 studies showed limited evidence of change in weight or body composition with use of POCs. Mean weight gain at 6 or 12 months was less than 2 kg (4.4 lb) for most studies. Those with multiyear data showed mean weight change was approximately twice as much at two to four years than at one year, but generally the study groups did not differ significantly. Appropriate counseling about typical weight gain may help reduce discontinuation of contraceptives due to perceptions of weight gain.

The Effect of Depo Medroxyprogesterone Acetate (DMPA) on Cerebral Food Motivation Centers: A Pilot Study using Functional Magnetic Resonance Imaging. Contraception 2016; 94:321-7. [PMID: 27129935 DOI: 10.1016/j.contraception.2016.04.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2015] [Revised: 04/12/2016] [Accepted: 04/15/2016] [Indexed: 11/30/2022]
Abstract
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.
