Fifteen studies of intervention programmes, one by the present authors, are discussed. Since non-intervention studies of water supply are difficult to assess, a valid study design must include an intervention programme, even though such studies are more costly and time-consuming. Detailed descriptions of programmes, study plans, and analytical methods are often lacking, and different studies reach greatly diverging conclusions. It may be proposed that studies based on “weak” methodology give a more positive impression of improved public health after improvement of water supply than do before–after studies using comparison groups.

During the attack, the child has nystagmus and is unable to stand without support. Initially, the attacks are frequent, later slowly disappearing. Nineteen children who were diagnosed in 19751981 participated in a followup study. Sixteen of them were examined with audiometry and electronystagmography. Age at onset was from 5 months to 8 years, and the symptoms disappeared after 3 months to 8 years. The follow-up was performed 13 to 20 years after diagnosis. Me&y-one percent developed migraine which is somewhat more than in a normal population of this age. Thirty-nine percent had a family history of migraine which is a figure considerably lower than in a migraine population. None still had vertigo or a balance disorder. Our conclusion is that benign paroxysmal vertigo has a favorable outcome, and it is not a general precursor of migraine.

Acta Paediatr Scand 77:260, 1988. In connection with the introduction of an improved method of water supply in rural Malawi, the nutritional status, morbidity, and mortality among 1178 children under five were studied during three rainy and three dry seasons. Data were collected at fortnightly home interviews. Nutritional assessment was made twice a year. One hundred and thirty-seven of the children died during the study period, and the probability of dying before the age of five was estimated to 270 per 1000 children. The mortality risk was related to weight for height (p<0.001) and height for age (p<0.01) as well as to upper arm circumference (p<0.001) and triceps skinfoid (p<0.05). Mortality among children living in households using the new, piped-water supply tended to be lower than mortality for those using traditional water sources, although the difference was not statistically significant (relative risk 0.4, 95% confidence interval 0.1-1.3).

Multiple subcutaneous tumors were found at birth in a pair of identical twins, and the histological diagnosis was neuroflbroma. The tumors disappeared within seven months. This disorder must be differentiated from congenital generalized fibromatosis, which usually shows a malignant course.

Compared with the reference population, newborn infants generally weighed less and were shorter. Breastfeeding was universal and appeared adequate for catch-up in weight during the 1st 3 months. Growth faltering occurred from the age of 3 months when the prevalence of infectious diseases gradually increased and suitable supplementary foods were lacking. Babies were given highly contaminated water from the 1st days of life, but, in spite of this, diarrhoea was infrequent during the 1st 5 months when respiratory tract infections and episodes of fever were the most common symptoms of disease. Diarrhoea became a problem from the age of 5-6 months. No differences in morbidity or growth patterns were observed between infants using piped and traditional water sources. Thus, the quality of drinking water seemed to have no substantial effect on the health of the studied infants during the 1st months of life.
