Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • Women only
  • Healthy volunteers accepted
  • Child, Adult, Older adult

A cluster was eligible to participate if it:

  • Is located in Kintampo North or South Districts (this is the core study area for KHRC)
  • Is primarily rural (in practice, this excludes Kintampo, which is a small city of approximately 40,000 people);
  • Is operationally feasible (in practice, this excluded a handful very small, isolated clusters that would have presented extraordinary logistical challenges);
  • Is home to women who primarily deliver at one of our four staffed birth facilities (in practice this excluded one village on the edge of the study area, in which women travel to another district for deliveries).

A woman will be eligible to participate in the study if she:

  • Is in the first or second trimester of pregnancy (gestational age ≤ 24 weeks gestation; this is to ensure that the intervention is actually delivered prior to 27 weeks)
  • Is carrying a live singleton fetus (twins will be excluded)
  • Is the primary cook in her household or compound; and
  • Is a non-smoker.

About this study

Official title: Intervening to Improve Birth Weight and Infant Respiratory Health in Rural Ghana

The purpose of the study is to understand how cooking might affect the health of pregnant women and their babies.

The goal of the research is to determine whether, interventions in decreasing exposure to smoke from cook stoves can bring about a significant change in the indoor air pollution levels and health of communities in Ghana.

Hypothesis 1. Use of improved cook stoves starting by the third trimester pregnancy will lead to a significant increase in average birth weight in newborns.

Hypothesis 2. Use of improved cook stoves will lead to a significant reduction in the rate of severe acute lower respiratory disease during the first 12 months of life.

Read the detailed description
  1. Overview of design and analysis [per CONSORT 2010] 2.1 Trial design [CONSORT 3a] The study is a three-arm cluster randomized trial, with two intervention arms and a control arm. The primary justification for intervening at the village level is that an individual level randomization, which would entail treatments and controls living side-by-side in a village, could lead to conflict within villages.

2.2 Study Participants [CONSORT 4a, 4b] The study will take place in the catchment area of Kintampo Health Research Centre. This comprises a population of 146,000. The study population is primarily rural and agricultural, and cooks primarily with biomass fuels. The study area is well described in Owusu-Agyei et al. 2012 (38).

A cluster was eligible to participate if it:

  • Is located in Kintampo North or South Districts (this is the core study area for KHRC)
  • Is primarily rural (in practice, this excludes Kintampo, which is a small city of approximately 40,000 people);
  • Is operationally feasible (in practice, this excluded a handful very small, isolated clusters that would have presented extraordinary logistical challenges);
  • Is home to women who primarily deliver at one of our four staffed birth facilities (in practice this excluded one village on the edge of the study area, in which women travel to another district for deliveries).

A woman will be eligible to participate in the study if she:

  • Is in the first or second trimester of pregnancy (gestational age ≤ 24 weeks gestation; this is to ensure that the intervention is actually delivered prior to 27 weeks)
  • Is carrying a live singleton fetus (twins will be excluded)
  • Is the primary cook in her household or compound; and
  • Is a non-smoker. 2.3 Interventions [CONSORT 5]

The study has three arms:

  1. LPG intervention arm, in which households receive a two burner LPG cookstove and monthly gas deliveries;
  2. An efficient biomass arm, in which households receive two BioLite cookstoves; and
  3. A control arm 2.4 Outcomes [CONSORT 6a]

The primary health outcome measures for the study are:

  1. Infant weight at birth, and
  2. Physician assessed pneumonia. Baseline assessments of outcomes No baseline data for ALRI prevalence from Ghana is available. Our study will thus provide very valuable baseline data regarding this important disease.

KHRC has, in the course of conducting other research projects, captured some information regarding birth weight; statistics calculated from these data were used as inputs into power calculations. These data are described in (39).

2.5 Sample size [CONSORT 7a, 7b] For the three-arm design, we calculate that we need to enroll households to achieve our target of 1225 births (assuming that 85% of the pregnancies will result in a recorded birth after, accounting for move out, drop out, and still birth rates). These will be spread across 35 or more clusters, as outlined in the following table.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cook stoves, either Biolite wood stove, or liquified petroleum gas stove plus fuelOther

    The cooking stoves will reduce air emissions significantly in the home, resulting in improved infant health. It will be given to the mother in the second or third trimester.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, Ghana. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

On the ClinicalTrials.gov record for NCT01335490, which also lists 9 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jul 2017.
