Facts about Malaria and Pregnancy
 30 million African women are pregnant yearly
 Malaria is more frequent and complicated during
pregnancy
 In malaria-endemic areas, malaria during pregnancy
may account for:
 Up
to 15% of maternal anemia
 5–14% of low birthweight
 30% of “preventable” low birthweight

Focused Antenatal Care
An approach to ANC that emphasizes:
 Evidence-based, goal-directed actions
 Individualized, woman-centered care
 Quality vs. quantity of visits
 Care by skilled providers
Prevention and Control of Malaria during Pregnancy

Goal of Focused Antenatal Care
To promote maternal and newborn health and survival
through:
 Early detection and treatment of problems and
complications
 Prevention of complications and disease
 Birth preparedness and complication readiness
 Health promotion
Prevention and Control of Malaria during Pregnancy

Traditional Antenatal Care
 Emphasizes:
 Ritualistic,
“routine” care vs. evidence-based,
goal-directed actions
 Frequent visits
 Does not emphasize individual client needs
Prevention and Control of Malaria during Pregnancy
10
No Longer Recommended
 Numerous, routine visits
 Burden to women and healthcare system
 Routine measurements and examinations:
 Maternal height and weight
 Ankle edema
 Fetal position before 36 weeks
 Care based on risk assessment
Prevention and Control of Malaria during Pregnancy
11
Risk Approach
Not an effective ANC strategy because:
 Complications cannot be predicted—all pregnant women
are at risk for developing complications
 Risk factors are usually not direct cause of complications
 Many “low risk” women develop complications
 Have false sense of security
 Do not know how to recognize/respond to problems
 Most “high risk” women give birth without complications
 Inefficient use of scarce resources

Intermittent Preventive Treatment
Although a pregnant woman with malaria may have
no symptoms, malaria can still affect her and her
unborn child
Prevention and Control of Malaria during Pregnancy
48
Intermittent Preventive Treatment:
WHO Recommendation
All pregnant women should receive at least two
doses of IPT after quickening, during routinely
scheduled ANC visits (WHO recommends a schedule
of four visits, three after quickening)
Presently, the most effective drug for IPT is
sulfadoxine-pyrimethamine (SP)
Women should receive at least two doses of IPT with
SP at ANC visits after quickening, but no more
frequently than monthly
Prevention and Control of Malaria during Pregnancy
49
Intermittent Preventive Treatment:
Dose and Timing
 A single dose is three tablets of sulfadoxine 500 mg
+ pyrimethamine 25 mg
 Healthcare provider should dispense dose and
directly observe client taking dose
Prevention and Control of Malaria during Pregnancy
50
Instructions for Giving Intermittent
Preventive Treatment
 Ensure woman is at least 16 weeks pregnant and

that quickening has occurred
Inquire about use of SP in last 4 weeks
Inquire about allergies to SP or other sulfa drugs
(especially severe rashes)
Explain what you will do; address the woman’s
questions
Provide cup and clean water
Prevention and Control of Malaria during Pregnancy
51
Instructions for Giving Intermittent
Preventive Treatment (cont’d.)
 Directly observe woman swallow three tablets of SP
 Record SP dose on ANC and clinic card
 Advise the woman when to return:
 For her next scheduled visit
 If she has signs of malaria
 If she has other danger signs
Reinforce the importance of using ITNs
