Abstract [en]

AIM: To describe the frequency of overweight and obesity from birth to 20 years of age and analyse weight at 20 years of age in relation to weight and weight development during early childhood and adolescence.

METHODS: A longitudinal, population-based study, which followed 496 children from birth to 20 years of age. Information about weight and height was collected from health records at child health centres and school health care. At 20 years of age, weight and height measurements were taken by one of the authors.

RESULTS: At 20 years of age, 124 (25%) of the youth were obese or overweight. Of these youths, 60% had normal weight at 5.5 years. Of the teenagers who were overweight/obese at 15 years, 79% remained overweight/obese at 20 years of age. Out of the 124 overweight/obese at 20, 47% had normal weight at 15 years. [Corrections added after online publication on April 18, 2012: 'Out of the 124 obese at 20' has been changed to 'Out of the 124 overweight/obese at 20']. No relation was found between rapid weight gain during preschool age and overweight and obesity in 20-year-olds.

CONCLUSIONS: The majority of those who were overweight/obese at 20 years of age were recruited after 5.5 years of age, and half of them in their late teens. Thus, during the preschool period, the entire population should be the target of primary prevention from overweight/obesity and, in the case of teenagers, prevention strategies should be developed for the whole population as well as treatment strategies for teenagers with established overweight/obesity.

Abstract [sv]

Fetma är en av världens snabbast växande sjukdomar och karies är fortfarande en vanlig sjukdom hos barn och ungdomar. Syftet med denna licentiatavhandling har varit att:

  1. beskriva frekvensen av övervikt och fetma från födseln till tjugo års ålder.
  2. analysera vikt och viktutvecklingen från födseln till vuxen ålder.
  3. undersöka prevalens av approximal karies hos femtonåringar i förhållande till deras åldersspecifika BMI (isoBMI).
  4. undersöka tidiga mellanmålsvanor och karies vid femton års ålder.

I studien ingick 671 barn följda från 1 till 20 års ålder. Studien har en populationsbaserad longitudinell design och analyserna baserar sig på uppgifter från barnhälsovårds (BHV) -, skolhälsovårds (SHV)- och folktandvårdsjournaler (FTV) från fyra distrikt i Jönköpings kommun. Längd, vikt och födelsediagnoser är inhämtade från BHV- journaler. Från SHV journaler inhämtades längd och viktuppgifter vid 15 år och från FTV journaler inhämtades uppgifter om kariesförekomst vid 15 och 20 års ålder. Dessutom inhämtades data från intervjuer och frågeformulär, som samlats in då barnen var 1 och 3 år gamla. Studien visade att det finns ett samband mellan övervikt/fetma vid 20 års ålder och övervikt/fetma vid 5½ och 15 års ålder. Emellertid var 70 % av dem som hade övervikt/fetma vid 20 år normalviktiga vid 5½ år och 47 % av dem med övervikt/fetma var normalviktiga vid 15 års ålder.

Studien visade också att tonåringar med övervikt och fetma hade en signifikant högre prevalens av approximal karies än de som var normalviktiga. Vidare påvisades ett samband mellan förtäring av kariesriskprodukter vid 1 och 3 år och kariesförekomst vid 15 år. Det framkom inget samband mellan födelsevikt och senare övervikt/fetma vid 20 års ålder. Studien visade inte heller något tydligt mönster av viktutvecklingen från tidig barndom till ung vuxen. Ett barn kunde t ex ha övervikt vid ett mättillfälle för att vid nästa mättillfälle vara normalviktig och sedan överviktig igen. Framtida preventionsprogram för att förebygga både fetma och karies bör samordnas mellan de olika hälsoprofessionerna. Med tanke på att minst hälften av individer som utvecklar övervikt/ fetma till 20 års ålder rekryterades efter 15 års ålder bör denna tonårsgrupp ges särskild uppmärksamhet och nya former för prevention och behandling behöver utvecklas. För barn i förskoleåldern bör primär prevention riktas till hela populationen.

Abstract [en]

Obesity is one of the most rapid growing illnesses and dental caries is still a common illness by children and youth. The aims of this licentiate thesis were:

  1. describe frequency of overweight and obesity from birth to twenty years of age.
  2. analyze weight and weight development from birth to adult age.
  3. examine prevalence of approximal dental caries by teenagers fifteen years of age comparing to their age-specific BMI (isoBMI).
  4. examine early snacking habits and dental caries at the age of fifteen.

The investigations have a population based longitudinal design and the analyses are based on data from 671 children followed from birth to 20 years of age. Information about weight and height were collected from health records at child health centers and school health care. At 20 years of age, weight and height measurements were performed by one of the authors. Data were also selected from caries examinations, interviews and questionnaires when the children were 1 and 3 years of age and from the children’s bitewing radiographs at 15 years of age. The result showed an association between overweight/obesity at 20 years and overweight/obesity at 5½ and 15 years. However, 70% of those who were overweight/obese at 20 years were of normal weight at 5½ years and 47% at 15 years. The majority of those who were overweight/obese at 20 years of age were recruited after 5.5 years of age and half of them in their late teens.

Another finding was that overweight and obese adolescents had more approximal caries than normal-weight adolescents. Furthermore, consumption of snacking products and soft drinks at an early age appears to be associated with caries at 15 years of age. There was no connection found between birth weight and later overweight/obesity at 20 years of age. The study could not demonstrate any distinct patterns of the weight development from early childhood to young adult. A child could, for example, have overweight/obesity at one measurement, have normal weight at the next and then again have overweight/obesity at the third measurement. Because dental caries and overweight/obesity have common determinants further prevention measures should include strategies to prevent and reduce both overweight/obesity and dental caries in the young population.

During the preschool period, the entire population should be the target of primary prevention from overweight/obesity, while, in the case of teenagers, prevention strategies should be developed for the whole population and treatment strategies for teenagers with established overweight/obesity.
