Does anyone know of any research or practical interventions that have investigated plausible time frames for the rehabilitation of children under the age of 24 months with stunting? I am trying to get an idea of how long it might take to reverse the effects of stunting in terms of sex-matched height for age. Obviously in order to effectively address stunting, all key causes will need addressing in parallel. But assuming they are, the issue is complicated by the fact that growth is episodic, with long periods of stasis (between 2 and 63 days) punctuated by short phases of saltation (growth spurts), so that there is no growth during 90–95% of healthy infancy. We know that effects of both severe and moderate acute MN can be reversed in a matter of weeks, whereby 60 days is usually set as a cut-off for non-response. But is there something similar for stunting? I am assuming the timeframe will differ for cases of severe stunting and moderate stunting, although maybe catch-up growth is more rapid in severe cases, so the overall timeframe may be similar. Or maybe timeframes will differ for both severe and moderate, but also by age groups i.e. severe stunting 0-6m, 6-12m, 12-24m and moderate stunting 0-6m, 6-12m, 12-24m. Any guidance would be very much appreciated....
