Indicator Phrasing

English: % of children aged 8 - 23 / 59 months which in the past two weeks had at least 3 loose or liquid stools in one day

French: % d'enfants âgés de 8-23 / 59 mois qui au cours des deux dernières semaines ont eu 3 ou plus de selles molles en un jour

Spanish: % de niños de 8 a 23 / 59 meses que en las últimas dos semanas han hecho al menos 3 deposiciones líquidas o blandas en un día

Portuguese: % de crianças com idades entre 8 -23 / 59 meses que nas duas semanas anteriores tiveram pelo menos 3 evacuações de fezes soltas ou líquidas num só dia

Czech: % dětí ve věku 8-23 / 59 měsíců, které v uplynulých 2 týdnech měly během jednoho dne alespoň 3 řídké stolice

What is its purpose?

The indicator assesses the percentage of children who suffered from diarrhoea in the past two weeks (one of the leading causes of child death). Diarrhoea is defined as having 3 or more loose or liquid stools in one day.

How to Collect and Analyse the Required Data

Collect the following data by conducting individual interviews with mothers of (a representative sample of) children aged 8 - 23 / 59 months:

   

RECOMMENDED SURVEY QUESTIONS (Q) AND POSSIBLE ANSWERS (A)

Q1: In the past two weeks, did [name of the child] have diarrhoea?

A1: yes / no / does not remember / not applicable

  

(ask the next question only if the previous answer is YES)

  

Q2: During this time, did s/he pass 3 or more loose stools in the course of one day?

A2: yes / no / does not remember

    

To calculate the indicator's value, divide the number of children aged 8 - 23 / 59 months who had 3 or more loose stools per day by the total number of surveyed children in the past two weeks. Multiply the result by 100 to convert it to a percentage.

Disaggregate by

Disaggregate the data by gender, age groups, and wealth.

Important Comments

1) WHO's definition of diarrhoea is "the passage of three or more loose or liquid stools per day". However, the vast majority of surveys do not enquire whether the child had three (or more) loose stools in one day - most commonly, they just ask: “Has (NAME) had diarrhoea in the last 2 weeks?” (i.e. it is left up to the respondent to decide whether the loose / liquid stool really was diarrhoea or not). You have to decide whether your survey will assess and consider the frequency of loose stool (as suggested above) or whether it will follow the methodology commonly used by other surveys (such DHS or MICS). If you choose the latter option, ensure that the enumerators are very clear about (and can explain) what is understood as diarrhoea. 

 

2) This indicator relies on accurate age assessment. Since people often do not remember the exact dates of their children’s birth, the data collectors should always verify the child’s age. This can be done by reviewing the child’s birth certificate, vaccination card or another document; however, since many caregivers do not have such documents (and since they can include mistakes), it is essential that your data collectors are able to verify the child’s age by using local events calendars. Read FAO’s Guidelines (see below) to learn how to prepare local events calendars and how to train data collectors in their correct use.

    

3) The stool of children aged up to 8 months is naturally loose and may not indicate diarrhoea. Therefore, include in your survey children aged 8 - 23 / 59 months only.

    

4) A standard recall period of two weeks is commonly used by most agencies. However, a number of pieces of research showed that such a long recall period leads to imprecise data that underestimates diarrhoea prevalence by up to 45% (for example, 12) . If your data does not need to be comparable with other surveys (e.g. is used only for comparing your project's baseline and endline values), consider using a shorter recall period of 7 days (for maximum precision, you can also use a 3 day recall period though this will require increasing the sample size by approx. 70%). Always ensure that both baseline and endline surveys use the same recall period.

  

5) The prevalence of diarrhoea is often prone to seasonal differences. Do your best to collect baseline and endline data in the same period, otherwise it is very likely that they will not be comparable (i.e. saying little about the benefits of your project).
