RESUMO
BACKGROUND: The use of silver diamine fluoride (SDF) as a nonsurgical caries management product is growing. Evidence suggests that SDF is very successful in arresting caries. However, a common concern with SDF treatment is the unaesthetic black staining. The purpose of this qualitative study was to determine parents' views following their children's treatment with SDF to manage severe early childhood caries (ECC). METHOD: Parents were interviewed as part of a mixed-method study of SDF to arrest severe ECC. Children with caries lesions in primary teeth were treated with 2 applications of 38% SDF, followed by fluoride varnish. Semistructured in-person and phone interviews were conducted with 19 parents of children in the study. Data were transcribed verbatim and manually coded and uploaded to NVivo 12 for further coding analysis. RESULTS: None of the parents had previously heard about SDF, and they learned about it from the study dentist. Although parents trusted the dentist's information on SDF, they welcomed additional evidence, especially relating to product safety and effectiveness. Some parents were minimally concerned with the black staining caused by SDF treatment. It was more important that SDF arrested caries progression, minimized pain and sensitivity, and prevented dental infection. However, some parents expressed concerns related to the unaesthetic black staining. Interestingly, many parents indicated that their children were not overly concerned with the black staining. A majority of parents said that they would recommend the treatment to others. CONCLUSION: This is the first qualitative study involving parents of children who were treated with SDF. Most parents were accepting of SDF as a nonsurgical treatment to arrest caries and minimize dentinal sensitivity secondary to caries, although some expressed concern about the black staining in anterior teeth. It is important to adequately inform parents of the negative aesthetic consequences and obtain informed consent before treatment. KNOWLEDGE TRANSFER STATEMENT: This qualitative study revealed that many parents of children with severe ECC are accepting of SDF as a nonrestorative caries management option, despite the black staining of caries lesions. Dental professionals need to be aware of these parental concerns and obtain written informed consent prior to treatment. Parents also requested more information and resources on SDF on its benefits, effectiveness, and any associated risks.

The purpose of this study was to assess the relationship between vitamin D status and dental caries in Canadian school-aged children participating in the Canadian Health Measures Survey (CHMS). The CHMS was a national cross-sectional study involving physical assessments, laboratory analysis, and interviews. Analysis was restricted to data for 1,017 children 6 to 11 y of age. Outcome variables included the presence of caries and overall total caries score (dmft/DMFT index). Levels of 25-hydroxyvitamin D (25(OH)D) were measured from serum samples obtained from participants. Bivariate analysis, logistic regression for the presence of caries, and multiple linear regression for total caries scores were used. Significance was set at P ≤ 0.05. Overall, 56.4% of children experienced caries, and the mean dmft/DMFT score was 2.47 (95% CI 2.09 to 2.84). The unadjusted odds of children with 25(OH)D levels ≥75 nmol/L having experienced caries was 0.57 (95% CI 0.39 to 0.82), while the odds for caries at the ≥50 nmol/L level was 0.56 (95% CI 0.39 to 0.89). After controlling for other covariates, backward logistic regression revealed that the presence of caries was significantly associated with 25(OH) levels <75 nmol/L and <50 nmol/L, lower household education, not brushing twice daily, and yearly visits to the dentist. Similarly, multiple linear regression revealed that total dmft/DMFT caries scores were also associated with 25(OH)D concentrations <75 nmol/L, not brushing twice daily, lower household education, and yearly visits to the dentist. Data from a cross-sectional, nationally representative sample of Canadian children suggest that there is an association between caries and lower serum vitamin D. Improving children's vitamin D status may be an additional preventive consideration to lower the risk for caries.

BACKGROUND: Standing balance deficits are common in individuals after stroke. One way to address these deficits is to provide the individual with feedback from a force platform while balance activities are performed. The feedback can take visual and/or auditory form. OBJECTIVES: To determine if visual or auditory force platform feedback improves the clinical and force platform standing balance outcomes in clients with stroke. SEARCH STRATEGY: We searched the Cochrane Stroke Group trials register (last searched December 2003), and the following electronic bibliographic databases: the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 3, 2003), MEDLINE (1966 to May 2003), EMBASE (1974 to May 2003), CINAHL (1982 to May 2003), PEDro (May 2003), CIRRIE (May 2003) and REHABDATA (May 2003). Reference lists of articles were reviewed and manufacturers of equipment were contacted. SELECTION CRITERIA: Randomized controlled trials comparing force platform with visual feedback and/or auditory feedback to other balance treatments. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trials for inclusion, methodological quality, and data extraction. Trials were combined for meta-analysis according to outcome and type of feedback. MAIN RESULTS: We included seven trials (246 participants). Force platform feedback did not improve clinical measures of balance when moving or walking (Berg Balance Scale and Timed Up and Go). Significant improvements in laboratory force platform indicators of stance symmetry were found for regimens using visual feedback (standardised mean difference (SMD) -0.68, 95% confidence interval (CI) -1.31 to -0.04, p = 0.04) and the concurrent visual and auditory feedback (weighted mean difference (WMD) -4.02, 95% CI -5.99 to -2.04, p = 0.00007). There were no significant effects on laboratory postural sway indicators, clinical outcomes or measures of function at follow-up assessment. REVIEWERS' CONCLUSIONS: Force platform feedback (visual or auditory) improved stance symmetry but not sway in standing, clinical balance outcomes or measures of independence.

BACKGROUND: Chronic renal failure patients are at particular risk of hepatitis B virus infection. Early studies have demonstrated that renal failure patients benefit from vaccination; however, not all studies have consistently shown benefit. OBJECTIVES: To determine the beneficial and harmful effects of hepatitis B vaccine and of a reinforced vaccination series in chronic renal failure patients. SEARCH STRATEGY: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Renal Group Controlled Trials Register, The Cochrane Controlled Trials Register on The Cochrane Library (Issue 1, 2002),PubMed/MEDLINE (1966 to July 2003), EMBASE (1985 to November 2003), Current Clinical Practice Guidelines (Canadian Immunization Guide and Vaccine Preventable Diseases Surveillance Manual), and Science Citation Index as well as journals, published abstracts, and reference lists of articles. SELECTION CRITERIA: Randomised clinical trials comparing plasma vaccine with placebo, recombinant vaccine with placebo, recombinant vaccine with plasma vaccine, and a reinforced vaccination series (ie, more than three inoculations) with three inoculations of vaccine in chronic renal failure patients. DATA COLLECTION AND ANALYSIS: Primary outcome measures included incidence of patients developing hepatitis B virus antibodies and infections while secondary outcomes included adverse events, liver-related morbidity, and mortality. Random effects models were used and reported relative risks and 95% confidence intervals (RR and 95% CI). MAIN RESULTS: We included seven randomised clinical trials. None of them had high quality. Plasma vaccine was significantly more effective than placebo in achieving hepatitis B antibodies (RR 23.0, 95% CI 14.39 to 36.76, 3 trials). We found no statistically significant difference between plasma vaccine or placebo regarding hepatitis B virus infections (RR 0.50, 95% CI 0.20 to 1.24). We found no statistically significant differences between recombinant vaccine and plasma vaccine in achieving hepatitis B antibodies (RR 0.65, 95% CI 0.28 to 1.53, 2 trials). Heterogeneity was significant and appeared to be attributable to the dose of vaccine. Two trials examined a reinforced recombinant vaccine strategy, which was not statistically more effective than three inoculations of recombinant vaccine regarding development of hepatitis B antibodies (RR 1.36, 95% CI 0.85 to 2.16). REVIEWERS' CONCLUSIONS: Plasma derived vaccines are more effective than placebo in achieving hepatitis B antibodies, while no statistically significant difference was found between recombinant and plasma vaccines. No statistically significant difference of effectiveness was observed between a reinforced vaccination series versus routine vaccinations of three inoculations of recombinant vaccine.

BACKGROUND: Otitis media is a common pediatric problem, for which antibiotics are frequently prescribed. OBJECTIVES: To determine the effectiveness of a short course of antibiotics (less than seven days) in comparison to a longer course (seven days or greater) for the treatment of acute otitis media in children. SEARCH STRATEGY: The medical literature was searched for randomized controlled studies of the treatment of ear infections in children with antibiotics published from January 1966 to July 1997. Search last updated March 1998. SELECTION CRITERIA: Studies were included if they met the following criteria: subjects one month to 18 years of age, clinical diagnosis of ear infection, no previous antimicrobial therapy and randomization to treatment with less than seven days versus seven days or more of antibiotics. DATA COLLECTION AND ANALYSIS: Data on treatment outcomes were extracted from individual studies, and combined in the form of a summary odds ratio. A summary odds ratio (OR) equivalent to one indicated that the treatment failure rate following less than seven days of antibiotic treatment was similar to the failure rate following seven days or more of antibiotic. MAIN RESULTS: The summary OR for treatment outcomes at eight to 19 days in 1,524 children treated with short-acting antibiotics for five days versus eight to 10 days was 1.52, 95% CI: 1.17-1.98, but by 20 to 30 days outcomes between treatment groups (n=2,115) were comparable (OR=1.22, 95% CI:0.98-1.54). The absolute difference in treatment failure (Random effects model RD=2.9%, 95%CI:-0.3% to 6.1%) at 20 to 30 days suggests that at minimum 17 children would need to be treated with the long course of short-acting antibiotics to avoid one treatment failure. Similarity in outcomes was observed for up to three months following therapy (OR=1.16,95% CI=0.9-1.5). Comparable outcomes were shown between treatment with ceftriaxone or azithromycin, and more than seven days of other antibiotics. REVIEWER'S CONCLUSIONS: This review suggests that five days of short-acting antibiotic is effective treatment for uncomplicated ear infections in children.

BACKGROUND: Previous studies have suggested changes in self-concept with successful treatment of primary nocturnal enuresis (PNE), but behavioral changes have not been reported as a consistent associated finding. OBJECTIVE: To determine if self-concept and behavior change after 6 months of treatment of monosymptomatic PNE by conditioning alarm or desmopressin acetate (DDAVP). DESIGN: Randomized, controlled trial in an inner-city hospital clinic. Subjects were 182 children referred or recruited through media publicity, randomly assigned both to 1 of 8 pediatricians and 1 of 3 treatment groups (alarm, DDAVP, or placebo). Included were children >7 years old with PNE, no daytime symptoms, bladder capacity >50% expected, and wetting >3 times a week. Excluded were children with central nervous system disorders or developmental delays, and those currently on DDAVP or alarm. Subjects completed the Piers-Harris Children's Self-Concept Scale and Harter's Perceived Competence Scale for Children (PCSC) at initial visit and after 6 months of treatment. Parents completed the Achenbach Child Behavior Checklist (CBCL) at the same times. RESULTS: After 6 months of treatment the Piers-Harris total score showed a highly significant treatment by period interaction effect for DDAVP, a significant effect for alarm, and no effect for placebo. For children who achieved 75% dryness the CBCL showed a treatment by improvement interaction effect that was highly significant for DDAVP and placebo with no effect for alarm. For the PCSC there were no treatment or outcome interaction effects. After 6 months of treatment there were significant changes over time unrelated to outcome or treatment in the Piers-Harris Subscales and in the CBCL Internalizing and Externalizing Scores, and the Social Thought and Attention Problems Subscales. The PCSC was more stable with no changes in total score, and positive changes over time in only 2 Subscales, Scholastic and Social. CONCLUSION: Children's self-concept improved with the type of treatment and amount of success. Parents' perceptions of behavior improve with type of treatment and amount of success. Children rate their self-concept and some physical attributes better after treatment with any of DDAVP, alarm, or placebo regardless of outcome. Frequent follow-up with emotional support and encouragement appear to be important components of an efficacious intervention for children with nocturnal enuresis.

OBJECTIVES: To document current bicycle helmet use in Winnipeg, Manitoba and nearby rural communities, and to identify target groups for a helmet promotion campaign. METHODS: Cyclist helmet use was observed between 28 May and 20 August 1996 at a sample of urban and rural locations. Age, gender, helmet use, riding companion(s), location type, correct helmet use, and use of headphones were recorded. Univariate and multivariate analyses were performed. Adjusted odds ratios with 95% confidence intervals were calculated from the final models. RESULTS: Altogether 2629 cyclists (70% male, 30% female) were observed: 2316 at 183 urban locations and 313 at 25 rural locations, with nearly equal numbers of children and adults observed. Overall helmet use was 21.3%, with lower use in males (18.9%) than females (26.3%), despite gender only being a significant variable on multivariate analysis for children under 8 years and adults. Urban helmet use was considerably higher (22.9%) than rural use (8.9%). Helmet use increased linearly as mean neighbourhood income increased, with a nearly fourfold difference in use between the highest and lowest income neighbourhoods. Children less than 8 years old and adults had the highest, and teenagers the lowest, use. Significant predictive variables were identified separately by age category to inform targeted programming. CONCLUSIONS: We documented low helmet use in our region, emphasizing the need for a regional helmet promotion campaign as well as future helmet legislation. A marked urban-rural difference in helmet use that has not been previously reported was also identified. Target groups for a future campaign include adolescents, males, rural cyclists, and those in lower income neighbourhoods.

OBJECTIVE: To evaluate and summarize the house fire injury prevention literature. METHODS: MEDLINE (1983 to March 1997) was searched by keyword: fire, burn, etiology, cause, prevention, epidemiology, and smoke detector/alarm. ERIC (1966 to March 1997) and PSYCLIT (1974 to June 1997) were searched by keyword: as above, and safety, skills, education, and training. Other sources included references of retrieved publications, review articles, and books; Injury Prevention hand search; government documents; and internet sources. Sources relevant to residential fire injury prevention were selected, evaluated, and summarized. RESULTS: Forty three publications were selected for review, including seven randomized controlled trials, nine quasiexperiments, two natural experiments, 21 prospective cohort studies, two cross sectional surveys, one case report, and one program evaluation. These studies examined the following types of interventions: school (9), preschool (1), and community based educational programs (5); fire response training programs for children (7), blind adolescents (2), and mentally retarded adults (5) and children (1); office based counseling (4); home inspection programs (3); smoke detector giveaway campaigns (5); and smoke detector legislation (1). CONCLUSIONS: This review of house fire prevention interventions underscores the importance of program evaluation. There is a need for more rigorous evaluation of educational programs, particularly those targeted at schools. An evidence based, coordinated approach to house fire injury prevention is critical, given current financial constraints and the potential for program overload for communities and schools.

OBJECTIVE: To summarize house fire injury risk factor data, using relative risk estimation as a uniform method of comparison. METHODS: Residential fire risk factor studies were identified as follows: MEDLINE (1983 to March 1997) was searched using the keywords fire*/burn*, with etiology/cause*, prevention, epidemiology, and smoke detector* or alarm*. ERIC (1966 to March 1997) and PSYCLIT (1974 to June 1997) were searched by the above keywords, as well as safety, skills, education, and training. Other sources included: references of retrieved publications, review articles, and injury prevention books; Injury Prevention journal hand search; government documents; and internet sources. When not provided by the authors, relative risk (RR), odds ratio, and standardized mortality ratios were calculated, to enhance comparison between studies. RESULTS: Fifteen relevant articles were retrieved, including two case-control studies. Non-modifiable risk factors included young age (RR 1.8-7.5), old age (RR 2.6-3.6), male gender (RR 1.4-2.9), non-white race (RR 1.3-15.0), low income (RR 3.4), disability (RR 2.5-6.5), and late night/early morning occurrence (RR 4.1). Modifiable risk factors included place of residence (RR 2.1-4.2), type of residence (RR 1.7-10.5), smoking (RR 1.5 to 7.7), and alcohol use (RR 0.7-7.5). Mobile homes and homes with fewer safety features, such as a smoke detector or a telephone, presented a higher risk of fatal injury. CONCLUSIONS: Risk factor data should be used to assist in the development, targeting, and evaluation of preventive strategies. Development of a series of quantitative systematic reviews could synthesize existing data in areas such as house fire injury prevention.

OBJECTIVES: To describe the patterns of protective equipment use by in-line skaters in Winnipeg, Manitoba and nearby rural communities. METHODS: In-line skaters were observed for three months in 1996 at 190 urban and 30 rural sites selected using a formal sampling scheme. Age, gender, protective equipment use, skating companions, correct helmet use, and use of headphones were recorded. RESULTS: Altogether 123 in-line skaters were observed at 61 sites, including one rural site. No skaters were observed at the remaining sites. There were 37 adults and 86 children; 56% were male. Helmet use was 12.2% (95% confidence interval (CI) = 6.4% to 18.0%), wrist guard use was 16.3% (95% CI = 9.7% to 22.8%), knee pad use was 9.8% (95% CI = 5.2% to 16.4%), and elbow pad use was 7.3% (95% CI = 3.4% to 13.4%). Children were more likely to wear a helmet than teens 12-19 years of age (relative risk (RR) = 30, 95% CI = 4.01 to 225). Adults were more likely to wear wrist guards than children (RR = 4.32, 95% CI = 1.87 to 9.94). No gender differences were found. Incorrect helmet use was documented in four skaters; three skaters were wearing headphones. CONCLUSIONS: Low rates of protective equipment use were documented in our region, significantly lower than those reported in the literature. Barriers to equipment use are not known, and should be examined by further study. In-line skating safety programs should be developed, promoted, and evaluated. Teens should be targeted for future preventive efforts.

OBJECTIVE: To conduct a meta-analysis of randomized controlled trials of antibiotic treatment of acute otitis media in children to determine whether outcomes were comparable in children treated with antibiotics for less than 7 days or at least 7 days or more. DATA SOURCES: MEDLINE (1966-1997), EMBASE (1974-1997), Current Contents, and Science Citation Index searches were conducted to identify randomized controlled trials of the treatment of acute otitis media in children with antibiotics of different durations. STUDY SELECTION: Studies were included if they met the following criteria: subjects aged 4 weeks to 18 years, clinical diagnosis of acute otitis media, no antimicrobial therapy at time of diagnosis, and randomization to less than 7 days of antibiotic treatment vs 7 days or more of antibiotic treatment. DATA EXTRACTION: Trial methodological quality was assessed independently by 7 reviewers; outcomes were extracted as the number of treatment failures, relapses, or reinfections. DATA SYNTHESIS: Included trials were grouped by antibiotic used in the short course: (1) 15 short-acting oral antibiotic trials (penicillin V potassium, amoxicillin [-clavulanate], cefaclor, cefixime, cefuroxime, cefpodoxime proxetil, cefprozil), (2) 4 intramuscularceftriaxone sodium trials, and (3) 11 oral azithromycin trials. The summary odds ratio for treatment outcomes at 8 to 19 days in children treated with short-acting antibiotics for 5 days vs 8 to 10 days was 1.52 (95% confidence interval [CI], 1.17-1.98) but by 20 to 30 days outcomes between treatment groups were comparable (odds ratio, 1.22; 95% CI, 0.98 to 1.54). The risk difference (2.3%; 95% CI,-0.2% to 4.9%) at 20 to 30 days suggests that 44 children would need to be treated with the long course of short-acting antibiotics to avoid 1 treatment failure. This similarity in later outcomes was observed for up to 3 months following therapy (odds ratio, 1.16; 95% CI, 0.90-1.50). Comparable outcomes were shown between treatment with ceftriaxone or azithromycin, and at least 7 days of other antibiotics. CONCLUSION: This meta-analysis suggests that 5 days of short-acting antibiotic use is effective treatment for uncomplicated acute otitis media in children.

The baby-bottle tooth decay (BBTD) risk factor literature was critically assessed for strength of evidence, and the prevention literature for the identification of which risk factors are being addressed. "Inappropriate" feeding practices (non-nutritive sucking, prolonged bottle/breast feeding, nap-time feeding) are believed to cause BBTD. The association of these practices with BBTD is inconsistent and the strength of association varies greatly. These practices increase exposure to lactose, a cariogenic carbohydrate, but the current causation model fails to explain why the majority of children with these risk factors do not develop BBTD. The association of BBTD with low socioeconomic status is stronger and more consistent. Prevention has focused almost exclusively on education directed at changing the postnatal feeding practices despite the fact that teeth begin formation in utero. Prenatal deficiencies of calcium and vitamin D can lead to enamel defects, and enamel defects in turn predispose teeth to caries. Baby-bottle tooth decay is especially prevalent in Aboriginal people, for whom studies have consistently reported diets deficient in vitamin D and calcium. BBTD may be a consequence of the poor socioeconomic conditions and malnutrition. Perhaps more attention should be given to primary prevention.

Through a medical chart review, the prevalence of diagnosed diabetes mellitus in Inuit of the Keewatin District of the Canadian Northwest Territories was determined to be 0.27%. All cases were in adults, and no cases of gestational diabetes were noted. The prevalence and pattern of obesity were determined from measurements of body mass index (BMI), skinfold thickness, and waist-hip ratio obtained during the 1990-91 Keewatin Health Assessment Study. Thirty-one percent of 414 randomly identified adults (29% of men, 37% of women) were overweight (BMI > 27). Central fat patterning was more prevalent in women and less prevalent in men from the Keewatin compared to the general Canadian population. Comparison of skinfold thickness values to published measurements obtained from earlier arctic surveys supports the hypothesis that changes in diet and activity levels associated with urbanization have resulted in increased obesity in the Inuit.

OBJECTIVES: To determine if Randomized Controlled Trial (RCT) methodology was used appropriately in community health, we: (1) determined the proportion of non-randomized studies that should have been RCTs, and (2) assessed the quality of the RCTs. METHODS: The 1992 issues of six community health journals were manually searched. Intervention studies were analyzed. Studies that did not use randomization were analyzed for feasibility and practicality of RCT methods; RCTs were analyzed for quality using a checklist. RCTs were compared with community health RCTs from The New England Journal of Medicine. The proportion of studies meeting each criterion was determined. RESULTS: Fourteen percent of 603 studies were interventions and 4% were RCTs. Of those not using randomization, 42% should have. Mean RCT scores were significantly lower for the community health journals than for The New England Journal of Medicine. Many criteria important to quality scored poorly. CONCLUSIONS: RCTs are underused and lack methodologic rigor in community health. Conclusions regarding the effectiveness of interventions are therefore suspect.

Nocturnal enuresis (NE) is a common developmental symptom which, in a nonsupportive environment, might have negative effects on the growth of positive self-concept in children. A careful history and physical examination helps to establish a rapport with the child and family and can rule out important organic disease. Constipation might be a contributing factor and should be relieved when present. Treatments are available that can result in either a cure or symptomatic relief for approximately 80% of children older than 7 years. Children with monosymptomatic NE respond best to conditioning alarms or, as second-line therapy, to one of two classes of pharmaceuticals: desmopressin acetate or tricyclic antidepressants. Anticholinergic drugs might have a role in diurnal enuresis, but their role in NE with daytime symptoms is not yet established. Therapies such as hypnosis and dietary restriction have some promise but require additional study and are not recommended at the present time. Combined therapy with desmopressin and conditioning alarms might be helpful for some of the more resistant cases but also needs additional study. The management of NE requires an investment of time but is quite rewarding, because families that have had success are very grateful. Treatment might assist children in developing positive self-concept. The next decade promises new developments in our understanding of NE.

Since the Nutrition Canada Survey (1973) there has been clear evidence that Aboriginal people have low intakes of many nutrients such as iron, vitamin D, calcium, folate, vitamin A, and fluoride. Recent surveys suggest that the situation has not changed. Children are most likely to be affected clinically. More than half of Aboriginal children in some subpopulations in Manitoba suffer a period of iron deficiency, which may affect development. Nutritional rickets is still a common problem in Manitoba. We have seen cases of megaloblastic anemia due to folate deficiency. The relationship of the well-described low folate intake in pregnancy and birth defects has received no attention for the Aboriginal population. In a recent survey of Inuit children, dental caries of the primary teeth were present in over 70% of children, with a mean DMF (decayed, missing, and filled) index of 1.8 teeth in children under 2 and 9.5 in children 6 to 8 years. Although clinical vitamin A deficiency is not seen, there is now good evidence that subclinical deficiency increases susceptibility to infections. Although not all Aboriginal populations suffer all of these deficiencies, the problems are sufficiently widespread to suggest this is an urgent problem. It will not be solved simply by education. There must be a political will and a coordinated effort to make a balanced diet available to all at an affordable cost.

The population survey is an important tool in community health assessment, including the physical and psychological aspects of family health. It provides data on health status and health determinants not available from vital statistics and health service utilization. The Keewatin Health Assessment Study (KHAS), which was designed in collaboration with the Keewatin Regional Health Board (KRHB), surveyed a representative sample of the predominantly Inuit population in 8 communities in the central Canadian Arctic. The entire survey included 874 individuals in all age groups, of whom 440 were children and adolescents under 18 years of age, and consisted of questionnaires, clinical examination and laboratory tests. Of the large number of variables on which data were collected, some were of particular relevance to the health of children and the well-being of the family, including: (1) Child growth and development; (2) Nutrition and diet; (3) Social pathologies: suicide attempts and sexual abuse; (4) Oral health; and (5) Audiologic health. In addition to providing cross-sectional data, survey participants constitute a cohort which, if followed up longitudinally, can be used to determine the incidence of specific conditions and identify risk factors which promote or prevent their occurrence. An example of such a cohort study is one on acute respiratory infection. Surveys serve many functions--providing data for planning and evaluation, promoting community awareness of health issues, and addressing basic research questions. The KHAS is one of several surveys launched over the past several years which jointly will begin to provide a circumpolar perspective on the health of Inuit people.

This article reviews the theories and instruments used in 14 studies that measured social support levels of adolescent mothers. Two general trends were revealed, a tendency for researchers to: (1) avoid stating their theoretical perspective of social support and (2) develop new social support instruments rather than take advantage of those already in existence. Strategies are offered to match the social support theories and instruments with the particular study purpose and outcome variables. Use of both an established and a new social support instrument within the same study is recommended as a method of providing concurrent validation for the new instrument and promoting comparability across studies in different situations. Assessment of confounding among variables, construct overlap between measures, and the validity of social support and outcome instruments with adolescent mothers will promote a more accurate description of the role of social support in adolescent mothering.

OBJECTIVE: To determine the efficacy of iron-fortified infant formula in preventing developmental delays and abnormal behavior. DESIGN: Double-blind, randomized, controlled trial. SETTING: Urban hospital clinic. PARTICIPANTS: A total of 283 healthy, bottle-fed infants from very low income families. Children with prematurity, low birth weight, and major anomalies and those who had received more than 2 weeks of evaporated-milk feedings were excluded. The groups were similar for sociodemographic background variables. Fifty-eight infants (20.5%) dropped out before any outcome data were gathered; 225, 204, 186, and 154 remained at 6-, 9-, 12-, and 15-month assessments, respectively. INTERVENTION: Iron-fortified formula (12.8 mg iron per liter) versus regular formula (1.1 mg iron per liter). MAIN OUTCOME MEASURES: Iron status was measured on venous blood by determination of hemoglobin, serum iron and iron-binding capacity, serum ferritin, and free erythrocyte protoporphyrin values. The Bayley Scales of Infant Development (mental and psychomotor indexes) and two factors of the Infant Behavior Record (test affect and task orientation) were the outcomes of interest. RESULTS: All measures of iron status were significantly different between groups (p < 0.001). Psychomotor development patterns differed between groups (F3,520, 3.4; p = 0.02) with time. Mean values were similar at 6 months but differed at 9 and 12 months of age (p < 0.001), with a decline of 6.4 points in the regular-formula group. By 15 months of age the differences were no longer significant (p = 0.23). Mental development and behavior were not affected. CONCLUSIONS: Iron-fortified formula significantly reduced iron deficiency in a high-risk group of infants and prevented a decline in psychomotor development quotients. This effect may be transient, and its long-term significance needs further study.
