Statement of problem•Antenatal polyclinic records ~ 35% of women, experienced complications during pregnancy or will have booked late or not at all.

•Were these women really concerned or did they want their pregnancy?

•Could this be the core issue resulting in late booking and subsequently, complications?

•Given the important associations of unintended pregnancies - what was the situation at Glenview polyclinic?

Objectives

1. To determine the proportion of unintended pregnancies.

2. To characterise the proportion of unintended pregnancies according to pregnancy number.

3. To ascertain the level to which certain factors are related to unintended pregnancy.

4. To make recommendations to appropriate stake holders.

Methodology (1)

DESIGN: Descriptive cross-sectional study

SETTING: Glenview polyclinic

SUBJECTS: Mothers attending child

immunisation, growth anddevelopment monitoring

sessions

SAMPLE SIZE: n > (1.96)2 x0.20(1-0.20)

(0.05)2

n > 246

SAMPLING METHOD: Convenience systematicsampling where all

mothers fromwhom informed consent hadbeen obtained were

interviewed

Methodology (2)

METHOD: Face-to-face interview using aquestionnaire

Shona questionnaire - (21 questions)

•Section A, towards mother

•Section B, partner details

Data management

DATA ENTRY: - Tally sheet

QUALITY CONTROL: - Verification between groups

DATA ANALYSIS: - Epi info version 6 analysed as case-referent study:

cases = unintended pregnancies referents = intended pregnancies

PRESENTATION: - PowerPoint descriptive statistics tables graphs

Results (1)

Table 2. Pregnancy results

Num ber Pregnancies 266 Mothers interviewed 135 Unintended pregnancies 84 I ntended pregnancies 182

Mean pregnancies per woman = 1.97

Proportion of unintended pregnancies = 31.6%

Results (2)

•Attributable to contraceptive failure (33/84) = 39.3%

[Attributable to oral contraceptives (29/33) = 87.9%]

•Acquired contraceptives from unregistered sources such as vendors at some point in their lives ~ 10%

Factors where p value > 0.05

Conclusions

•31.6% unintended pregnancies

•?? 2nd pregnancy most desired

•Associated factors:

e.g. considering abortion, not unmarried, age < 20, age > 30 and contraception failure significantly associated

Two major groups affected:

1. Women not married below the age of 20, not using contraception and with a possibly deceased mother.

2. Married women beyond their second pregnancies, who are using contraceptive pills and possibly more than 30 years old.

Recommendations

•ZNFPC - encourage use of other methods beyond 2nd pregnancy.

•Ministry of Health – Prevent sales of contraceptives from unregistered sources.

•Participants

•Nurses and staff at Glenview Polyclinic

•Supervisor - Mr S. Shamu

•Mr Ngulube – Shona translation
