Abstract
L
actose intolerance is a clinical syndrome that manifests with characteristic signs and symptoms upon the consumption of food substances containing lactose, a disaccharide. Significant changes in knowledge and approach toward LI have occurred over the past quarter century, since the first statement on LI was published by the American Academy of Pediatrics Committee on Nutrition. It is hoped that, health care professionals involved in a child’s health care will feel confident to give guidance on post-gastroenteritis secondary LI without referral to secondary or specialist care. Finally, management of LI globally will require both education and product development.
Aim of the Study:
This study aims to assess mothers’ knowledge and practice about the care for children suffering from LI.
Setting:
The study was conducted at Nutrition Clinic at specialized outpatient clinics in Children’s affiliated to Ain-Shams University Hospitals.
Subjects:
A convenience sample composed of all available mothers of children with confirmed diagnosis of LI, with characteristics as
1- Infant with age from 1 month to 1 year,
2- Child with age from 1 year to 12 years,
3- Adolescent from 12 years to 18 years.
Tools of Data Collection:
1- Pre-designed questionnaire sheet:
It was designed by the researcher after reviewing the relevant literature and was reviewed by the supervisors. It was written in a simple Arabic language to assess the following:
Demographic data: of mothers; included: age, number of children, kinship between mothers, family history of LI and level of education for mothers.
Characteristics of children such as: Age, gender, ranking, disease history.
Knowledge of the studied mothers about: LI disease in children, such as: Definition, causes, manifestations, complications and care.
Scoring system to Knowledge:
The studied mothers answers was compare with a model key answer, where (2) scores was given for completely correct answer, (1) score for incompletely correct answer and (0) for do not know the answer. Total score, 100% would categorize as the following according to mothers response, their level of knowledge would categorize as the following:
Good level ≥ 75%
Average level 60 < 75|%
Poor level < 60%
2- Practices of mothers during care of children with LI as: first: Anthropometric measurements: weight, length or height and head circumference. Second: nutrition (preparing of food, preparing of formula, feeding, and post feeding). Third: Activities, sleep, play and rest.
Scoring system to practice: Mothers practices was assessed by the researcher and scored as (1) score was given for correctly done, (0) score was given for incorrect done/ not done. Total score, 100% would categorize as the following according to the mothers actual practices:
Competent ≥ 85%
Incompetent < 85%
The main results of the study showed that:
The mean age of the studied children was 7.09±3.85.
Regarding gender 61% of them were from female.
Regarding ranking 48% of them were from the first rank children.

Majority (87%) of them was more than a year upon diagnosis;
Minority (22%) of children’s weight at diagnosis of LI, as well as the current weight of the children (25%) were not normal.
In addition, the result showed that, minority (12%) of studied children’s length at diagnosis, and the current children’s (15%) length not normal.
More than half (52%) of studied children suffering from LI has been hospitalized.
Also, the study finding demonstrated that, stomach cramps, diarrhea, bulge, dryness, and vomiting were the problems faced by the children suffering from LI.
The result showed that the mean age of studied father was 35.81±6.38 years old, also more than half of them had the university degree, and slightly less than half of father’s job was office job.

Finally, the research questions were confirmed by that, there was a positive correlation between mothers’ total score knowledge, practice and life of style about LI.
The study concluded that:
Based on the findings of the present study, the following could be concluded:
The research questions were confirmed by that, there were positive correlation between mothers’ total score knowledge, practice and life of style of a child with lactose intolerance.
