OBJECTIVE To determine the prevalence of macroalbuminuria and to describe the clinical and renal pathological changes associated with macroalbuminuria in a population of Canadian First Nation children and adolescents with type 2 diabetes. RESEARCH DESIGN AND METHODS We conducted a retrospective chart review at a single tertiary care pediatric diabetes center, and a case series was constructed. We collected data on microalbuminuria (≥3 mg/mmol creatinine [26.5 mg/g]) and macroalbuminuria (≥28 mg/mmol creatinine [247.5 mg/g]), estimated glomerular filtration rate, renal pathology, and aggravating risk factors (poor glycemic control, obesity, hypertension, glomerular hyperfiltration, hypercholesterolemia, smoking, and exposure to diabetes in utero). RESULTS We reviewed 90 charts of children and adolescents with type 2 diabetes. A total of 53% had at least one random urine albumin-to-creatinine ratio ≥3 mg/mmol (26.5 mg/g). There were 14 of 90 (16%) who had persistent macroalbuminuria at or within 8 years of diagnosis of diabetes. Of these 14 subjects, 1 had orthostatic albuminuria and 3 had spontaneous resolution of albuminuria. A total of 10 had renal biopsies performed. There were 9 of 10 who exhibited immune complex disease or glomerulosclerosis, and none had classic diabetic nephropathy. CONCLUSIONS This study suggests that the diagnosis of renal disease in children with type 2 diabetes cannot be reliably determined by clinical and laboratory findings alone. Renal biopsy is necessary for accurate diagnosis of renal disease in children and adolescents with type 2 diabetes and macroalbuminuria. The additional burden of nondiabetic kidney disease may explain the high rate of progression to end-stage kidney failure in this population.

Lifestyle intervention on diet and exercise reduced excessive gestational weight gain in pregnant women under a randomised controlled trial. BJOG 2012;119:70–77. Objective To examine the effect of an exercise and dietary intervention during pregnancy on excessive gestational weight gain (EGWG), dietary habit and physical activity in pregnant women. Design Randomised controlled trial. Setting Community‐based study. Population Nondiabetic urban‐living pregnant women (<26 weeks of gestation). Methods Participants in the intervention group were provided with community‐based group exercise sessions, instructed home exercise and dietary counselling between 20 and 36 weeks of gestation. Participants in both groups received physical activity and food intake surveys at enrolment and 2 months after the enrolment. Main outcome measures Prevalence of EGWG and measures of physical activity and food intakes between the two groups. Results A total of 190 pregnant women, 88 in the control group and 102 in the intervention group, completed the study. Decreased daily intakes of calorie, fat, saturated fat and cholesterol were detected in participants in the intervention group at 2 months after enrolment compared with the control group ( P < 0.01). Participants in the intervention group had higher physical activity 2 months after enrolment compared with the control group ( P < 0.01). The lifestyle intervention during pregnancy reduced the prevalence of EGWG in the intervention group compared with the control group ( P < 0.01) according to the guidelines of the Institute of Medicine. Conclusion The findings suggest that lifestyle intervention during pregnancy increased physical activity, improved dietary habits and reduced EGWG in urban‐living pregnant women.
