Abstract [en]

BACKGROUND: The prevalence of overweight and obesity in children is steadily increasing in many countries. Dental caries and obesity are both multifactorial diseases and are associated with dietary habits.

OBJECTIVE: The purpose of this study was to investigate the relationship between body weight status in adolescents and snacking habits in early childhood to approximal caries prevalence at 15 years of age.

METHODS: This study is part of a series of surveys of oral health in children followed from the ages of 1 year to 15 years. Body adiposity status was estimated at 13.5-16.4 years using the International Obesity Task Force cut-off values [age-specific body mass index (isoBMI)]. Information about snacking habits in early childhood was collected from interviews conducted at 1 year and 3 years. Approximal caries information was obtained from bitewing radiographs at 15 years. Data related to isoBMI and approximal caries were available in 402 teenagers.

RESULT: Adolescents with isoBMI > or = 25 (n = 64) had an approximal caries prevalence that was a mean of 1.6 times higher than those with isoBMI < 25 (n = 338) (4.64 vs. 2.94; P = 0.014). Furthermore, children's snacking habits at an early age were associated with approximal caries at 15 years.

CONCLUSION: Overweight and obese adolescents had more approximal caries than normal-weight individuals. Moreover, the frequent consumption of snacking products during early childhood appears to be a risk indicator for caries at 15 years. Future preventive programmes should therefore include, on a multidisciplinary level, strategies to prevent and reduce both obesity and dental caries at an early age.

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.
