Overview

Results from a one-year follow-up study with reversible method users conducted in Honduras, 2006-2007

The study was funded by USAID and implemented by MEASURE Evaluation in collaboration with Programas para el Desarollo de Infantes y Mujeres (PRODIM)

Contraceptive Discontinuation

Common, though varies by country

Most common during first 12 months of use

Contributes to unmet need

Can lead to unplanned pregnancy and unwanted births, resulting in negative public health outcomes

Objective

To determine how multiple factors affect contraceptive discontinuation among users of temporary methods over a one-year period Demographic characteristics

Fertility motivations

Partner engagement

Quality of FP services

Experience of side effects

Method characteristics

Study Sites

Data: Panel study collected in 2 rounds

Baseline exit interviews with 800 women aged 15-44, attending a FP appointment in selected health facilities in which they received the injectable, IUD, or oral contraceptive pill Women were both new and continuing users

There were no quotas by type of method

Follow-up interviews completed with 671 (84%) 1 year later

Study sample at baseline (n=671)

Young (94% under age 35)

Educated (30% reached secondary or higher)

Parity >/= 1

Married/in union (89%)

Urban residents (77%)

Desire to space a birth 2+ years (50%) or no more children (34%)

Method use by status of user at Baseline; N=671

Continuing (n=52%)

New Adopter (n=13%)

New Switcher (n=35%)

…But many switched to another method

Multivariate analysis: Cox proportional hazards models Model 1: Time until discontinuation of

baseline method

Model 2: Time until first episode of non-use of any method (Model 2)

Covariates: demographic characteristics, fertility motivations and family engagement, experience of side effects, baseline service quality, and user status at baseline

Stratified by baseline method

Discussion

More than 4 out of 10 women discontinued the baseline method

Living in rural areas may limit ability to successfully switch methods

Service quality had little effect on discontinuation

Family and friends may support continuation
