The importance of local data in unintended pregnancy prevention programming

Comparing the order of the London Measure of Unplanned Pregnancy and the Demographic and Health Survey question on pregnancy intention in a single group of postnatal women in Malawi - the effect of question order on assessment of pregnancy intention

Objective

To investigate the effect of question order on women’s responses to the London Measure of Unplanned Pregnancy (LMUP) or the pregnancy intention question of the Demographic and Health Survey (DHS) when both are asked in the same survey. We collected data on pregnancy intention from a cohort of 4244 pregnant women in Malawi who were re-interviewed at 1, 6 and 12 months postnatally. Women in Zone 1 were asked the LMUP, then antenatal questions, then the DHS pregnancy intention question, women in Zone 2 were asked the DHS pregnancy intention question, then antenatal questions, then the LMUP; women in Zone 3 were only asked the DHS pregnancy intention question. We used linear regression to compare the LMUP score and ordinal regression to compare DHS categorisations of pregnancy intention across Zones, adjusting for baseline socioeconomic differences between the Zones.

Results

We found no effect of question order on the assessment of pregnancy intention by the LMUP. There were differences in the assessment of pregnancy intention when the pregnancy intention question in the DHS was used, however this seemed to be due to baseline sociodemographic differences between the groups of pregnant women being compared, and not due to question order.

Usefulness of telephone risk factor surveys in the New Mexico border region

BACKGROUND

We sought to assess prevalence of behavioral risk factors and evaluate the usefulness of survey data gathered by telephone in the New Mexico border region.

METHODS

This study compared behavioral risk factor data gathered from two probability sample surveys administered in 1998-1999, one by means of a telephone interview and the second face to face. Prevalence estimates for medical care access, injury, and chronic disease risk factors were compared by survey mode, overall, and stratified by income level.

RESULTS

Risk factor prevalence estimates based on telephone interviews resemble estimates obtained from face-to-face interviews. Although risk factor prevalence estimated from face-to-face interviews were in general slightly greater than those from telephone interviews, none of these differences reached statistical significance. When data for each respective survey were examined by income level, prevalence estimates for comparable income groups in both surveys were in general agreement and estimates within survey increased with declining income.

CONCLUSION

In the New Mexico border region, telephone survey data appear to be reasonably valid and offer opportunities for population-based health research.
