Plain English summary of protocol
Background and study aims
Stunting is defined as having a height-for-age which is much lower than an internationally agreed average. Childhood stunting is a problem all over the world which can cause illness, disrupt development, and result in long-term consequences, including poor physical and cognitive health, and an increased likehood of developing diseases such as diabetes and heart disease later in life. Usually, interventions (treatments or programmes) looking to prevent or reverse stunting focus on the first 2 years of life, also known as the “1st 1000 days of life”. Children who slip through this net or become stunted later in life are therefore left behind. The period of adolescence, where rapid growth and development occur, may represent a “2nd window of opportunity” to optimise growth, development and health. It is also a key time for learning healthy lifestyles which may help prevent non-communicable diseases (NCDs) – such as diabetes or heart disease - in later life. However, little is known about whether steps taken to optimise growth and prevent NCD prevention during this time actually work. Researchers are currently looking to test a way of helping stunted adolescents, but first need to run this formative research (fact finding) project in order to as much information as possible to increase the possibility of success.
Who can participate?
Adolescents aged between 10 and 19 years in 2 different communities: rural Karonga and urban Lilongwe.
What does the study involve?
First of all, adolescents, their parents, and community leaders are all interviewed to ask their opinion of stunting, other diseases, causes of these diseases and how best to combat them. The adolescents also have their height, weight and body circumferences measured and are sked further questions about their health, family history and how their body is developing. Some of the adolescents are also asked to have some tests to see how active they are, how much fat and muscle they have in their body and brain function. These tests include wearing a device that measures how many steps they take each day, playing a computer game for 30 minutes while brain function is measured.
What are the possible benefits and risks of participating?
At this stage the only benefit to the participant is being able to influence the design of a future intervention (treatment) which you may be able to test at a later date. Participants that are found to have health issues are referred to the local health centre. There are no risks of taking part, as this study does not involve any invasive procedures.
Where is the study run from?
The study is run from a Wellcome Trust research site called MEIRU which has 2 locations: Karonga (in rural northern Malawi) and Lilongwe (the capitol city in Malawi)
When is study starting and how long is it expected to run for?
March 2016 to January 2017.
Who is funding the study?
The Wellcome Trust (grant number 200669/Z/16/Z)

| Scientific title | Growth in Adolescence: Potential interventions to improve growth and health and reduce the risks of future non-communicable disease: a cross-sectional pilot survey and interview study to inform a future RCT |
| Study acronym | GAP study |
| Study objectives | The aim of this study is to investigate the optimal interventional RCT for improving adolescent growth and health outcomes in Malawi |
| Ethics approval(s) | 1. College of Medicine Research Ethics Committee, Malawi (COMREC), 18/08/2016, ref P.06/16/1971 2. London School of Hygiene and Tropical Medicine Ethics Committee, 12/08/2016, ref 11689 |
| Health condition(s) or problem(s) studied | 1. Stunting 2. Increased risk of future non communicable disease (NCD) |
| Intervention | This observational research will take place in Karonga (rural site) and a Lilongwe (urban Site) in Malawi and will consist of: 1. Qualitative research: Key informant interviews with future study stakeholders will be conducted. Mainly individual interviews and some small focus groups. Approx. 20 individuals per study group are expected to achieve data saturation for interviews, and a maximum of 10 focus groups with a minimum of 4 participants. 2. A cross sectional survey: the primary aim of this is determine prevalence of stunting in adolescents in these communities. This will include primary data collection in Lilongwe, recruiting approx. 600 adolescents; and secondary data analysis in Karonga where basic anthropometry for all adolescents is already available 3. A detailed quantitative survey nested within the prevalence survey: More in-depth assessment of approximately 200 adolescents at each site will be conducted, including: a detailed questionnaire asking about possible risk factors for stunting/adverse long term outcomes; detailed anthropometry (following WHO recommended measurement methods); assessment of physical activity (using accelerometers); cognitive function (using CANTAB cognitive testing); and body composition by Bioelectrical Impedance Analysis or BIA (using Bodystat 1500MDD at 50Khz). Study questionnaires are based on existing validated tools including used in the Global School Heath Survey (GSHS), the Malawi Demographic Health Survey (DHS) and the FAO (Food and Agriculture Organization) 24 hour food recall sheet. Pubertal stage will be self-assessed using Tanner staging. The main target population are adolescents aged 10-19 years. In the qualitative sub-study carers/parents; teachers; community healthcare workers; other community leaders will also be interviewed. |
