Food and Nutrition Bulletin

Indonesia is a prime example of the triple burden of malnutrition. Indonesian adolescents are among the hardest hit, with approximately one in four adolescent girls suffering from anemia, while nearly one in seven adolescents is overweight or obese.

The present editorial provides a snapshot of the various research papers included in this Supplement, which calls for increased attention to adolescent nutrition in Indonesia and beyond.

Despite major steps to reduce undernutrition and overweight, including a renewed focus on anemia among adolescent girls, major gaps remain in our understanding of various nutrition issues concerning adolescents. These include various drivers and determinants of the triple burden of malnutrition, evidence-based interventions that are supported by large-scale implementation research and evaluation, and effective delivery platforms to reach the most vulnerable groups of adolescents.

The time has come to position adolescent nutrition as central to development, and mainstream it into health sector plans, strategies, and policies. It is our hope that this issue will stimulate the urgently needed interventions, implementation research and required programs that will safeguard the nutritional wellbeing of today's forgotten generation.

Recently, adolescence has been identified as a second window of opportunity for the correction of nutritional inadequacies. However, there is a lack of knowledge on evidence-based integrated nutrition strategies for adolescents in Indonesia.

To provide a research agenda and the prioritization of research actions to tackle outstanding knowledge gaps on adolescent nutrition in Indonesia.

A preliminary set of research topics was listed based on a desk study of the academic literature and policy documents. Second, a stakeholder meeting was held to further identify and discuss research topics related to adolescent nutrition in Indonesia. Third, an online survey was conducted in which respondents were asked to indicate priority research themes for the next 3 to 5 years and to rank a total of 23 research questions.

Most (52%) of the respondents who returned the survey (n = 27) prioritize research on implementation and program evaluation, while 30% prefer descriptive and explanatory research, and 19% place priority with intervention and discovery research. However, when we followed up with specific topics for each of these broad research areas, a more nuanced picture emerged, with intervention and discovery research taking a more prominent standing.

In order to support the design, implementation, and effectiveness of integrated nutrition programs for Indonesian adolescents, in-depth studies should question the best intervention strategies, modes of delivery, and long-term outcomes, while nationwide and disaggregated data should investigate associations and trends over time and identify vulnerable groups.

Previous studies have shown that sibling inequalities in overweight vary across contexts. Furthermore, research on the extent to which parental factors such as mother’s education can compensate for or reinforce such disparities is considerably rare.

This study analyzes to what extent and how the chances of overweight among children (0-19 years of age) vary systematically by gender, birth order, and number of siblings. We also look at whether mother’s education buffers or aggravates sibling inequalities in overweight.

Data were from the fifth wave of the Indonesian Family Life Survey-5 2014/2015, which comprised 6723 children born in 4784 families. We applied within-family centered birth order dummies to disentangle the effects of birth order from those of number of siblings. Cluster-robust logistic regressions were conducted.

Overweight occurred more in eldest and youngest children, and in children of smaller families. Mother’s education amplified sibling inequalities. Odds of overweight in children increased along with more years of education the mothers had. This was greater for boys and eldest children. Further analyses indicated that boys whose mothers spent more years in school consumed high-calorie foods more often.

The overall results indicate that mother’s education aggravates sibling inequalities in overweight. Nutrition interventions to reduce overweight in children should target the eldest and the youngest children and children of smaller families. Mothers who had more school years, and particularly their sons, should also be in the target group. Boys should be advised to consume high-calorie foods less often.

Anemia is a public health problem among adolescents in Indonesia. Strategies to prevent or treat anemia should be tailored to local conditions, taking into account its specific etiology and prevalence in a given setting and population group.

This review aims to (1) identify and synthesize the current knowledge on the etiology of anemia among adolescents in Indonesia, (2) reveal knowledge gaps in this area, and (3) suggest directions for future research and programmatic work.

We systematically searched PubMed, Web of Science, Scopus, Medline, and WorldCat databases for peer-reviewed journal articles to identify which etiological factors were related to anemia among Indonesian adolescents. Research papers were reviewed and included in the review according to inclusion criteria.

Of 13 studies, 8 showed that anemia was associated with iron deficiency; 4 are suggestive of vitamin A deficiency; and 2 of folic acid deficiency. Five studies underscore different etiological determinants for anemia, such as malaria, protein and energy malnutrition, vitamin B2 deficiency, calcium, and vitamin C deficiency. Based on these findings, we developed a framework on knowledge gaps on the etiology of anemia among adolescents in Indonesia, divided in 3 levels of knowledge: (1) significant knowledge gaps, (2) knowledge gaps, and (3) established knowledge.

The knowledge gaps around the etiology of anemia among Indonesian adolescents are significant. Our framework emphasizes the need for further research across all etiological factors, namely inadequate nutritional intake and absorption, genetic hemoglobin disorders, infection and inflammation, and menstrual disorders.

Anemia is a global public health concern. Its devastating consequences include impaired cognitive and motor development, reduced work productivity, and adverse birth outcomes, all of which apply to adolescents, as well as adults and children.

This study aimed to examine the determinants of anemia in Indonesian adolescent girls and boys from Klaten and Lombok Barat districts.

A total of 2150 adolescents who participated in a cross-sectional household survey were included in the analysis. The dietary intake of adolescents was assessed using a 7-day food frequency questionnaire. The relationship between anemia status, dietary intake, and other hypothesized determinants was assessed for adolescent girls and boys on a separate basis, using complex samples Cox regression analysis. Variables were selected for inclusion in multivariate models if they were significantly associated with the dependent variable in univariate models (P < .05).

The prevalence of anemia among adolescent girls and boys was 19% and 5%, respectively. In multivariate analyses, frequent consumption of animal-based iron-rich foods was significantly associated with a lower risk of anemia (prevalence ratio [PR]: 0.59; 95% CI: 0.36-0.97) among adolescent girls, whereas a higher intake of vitamin A-rich fruits and vegetables was associated with a reduced risk of anemia (PR: 0.41; 95% CI: 0.20-0.85) among adolescent boys, after adjustment for all potential confounders.

Increased consumption of iron- and vitamin A-rich foods through the implementation of gender-responsive Social Behaviour Change Communication (SBCC) interventions is warranted. This should be coupled with improved coverage and quality of iron and folic acid supplementation programs in adolescents.

Adolescent overweight and obesity (AOO) is a global public health problem and risk for noncommunicable diseases. Understanding context-specific risks is crucial for interventions.

Determine the prevalence of AOO in the Indonesian National Health Survey (INHS) 2013, assess the 5-year trend from 2013 to 2018, and identify risks.

We selected adolescents aged 10 to 19 years (n = 174 290) from the INHS 2013 and used hierarchical logistic regression to identify gender-specific risks for those aged 15 to 19 years (n = 77 534). Change in AOO was assessed by comparison to INHS 2018 reports.

The national AOO prevalence increased over 5 years by 48% in young adolescents (13-15 years) and 85% in older ones (16-18 years). High prevalence areas included the urban location of Jakarta (20.9%) and the remote rural region of Papua (19.4%). Overall, AOO risks were being sedentary, male, lower education, married, younger adolescent, and school enrollment, with urban residence and higher wealth being persistent risks for all analyses. Data for depressive symptoms were available for older adolescents whose additional risks were being sedentary, depressive symptoms, and high-fat diet. Male risks were being sedentary and lower education, and female risks were being married, depressive symptoms, high-fat intake, and lower education. Higher intake of fruits and vegetables and fewer sweets did not protect against AOO if a high-fat diet was consumed.

Adolescent overweight and obesity in Indonesia is rapidly increasing, especially in older adolescents and males, and with gender-specific risks. Customized multisectoral interventions to identify strategies for lifestyle change are urgently needed.

Crucial gaps persist in knowledge, attitude, and practice (KAP) of adolescent girls that affect anemia and linear growth failure.

To understand the role of KAP as a risk factor of anemia and linear growth problem in adolescent girls.

We conducted a cross-sectional survey of 335 adolescent girls selected by clustered random sampling. The KAP questionnaire had 18 variables consisting of 9 knowledge, 3 attitude, and 6 practice components. Twelve variables addressed nutrition, dietary diversity, and health environments related to both anemia and stunting. The questionnaire was adapted from the 2014 Food and Agriculture Organization nutrition-related KAP guidelines for anemia. Dietary practice was evaluated from 2-day 24-hour recalls and a semi-quantitative food-frequency questionnaire. Associations between KAP and anemia, and height-for-age z-score (HAZ), were analyzed using multivariate logistic and linear regression models, respectively.

The mean hemoglobin (Hb) level was 119.7 g/L, with 44% of the adolescent girls being anemic (Hb < 120 g/L) and mean height was 151.0 cm with 25% being stunted (HAZ < −2 standard deviation [SD]). The median KAP score was 7 and ranged from 3 to 10. Low to moderate KAP scores were not significantly associated with being anemic (adjusted odds ratio [AOR] = 1.26; P = .43), however 1-point KAP score increment was associated with an increase of HAZ by 0.037 SD (P = .012).

The KAP related to diet and healthy environments was not associated with anemia prevalence, but was positively associated with increased HAZ among adolescent girls. Strategy to reduce anemia risk in this population should combine KAP improvement with other known effective nutrition interventions.

Growing evidence highlights the linkage between body image, eating, and exercise behaviors among adolescents.

This study aims to determine the association between body image perception, nutritional status, and dietary and physical activity behaviors among adolescents in Indonesia.

A cross-sectional household survey was conducted among a representative sample (n = 2160) of adolescent girls and boys aged 12 to 18 years in Klaten and Lombok Barat districts. The association between adolescents’ body image, their diets, and physical activity patterns was determined using complex samples Cox’s regression analysis. Separate multivariate models were developed for adolescent girls and boys.

Physical appearance was considered important to nearly all adolescents. Approximately 11% of girls and 14% of boys were overweight or obese, the majority of whom (∼70%) correctly perceived themselves as overweight or obese. More of overweight or obese adolescents felt unhappy about their perceived weight than their thin counterparts. With respect to the overweight/obese girls, the adolescents’ perceptions of being overweight or obese was associated with a 63% reduction in the prevalence of overweight/obese girls consuming fatty snacks, such as deep-fried crackers (adjusted prevalence ratio (PR): 0.37, 95% confidence interval (CI): 0.19-0.71) and a 40% reduction in the prevalence of overweight/obese girls engaging in moderate-intensity physical activity (adjusted PR: 0.60, 95% CI: 0.38-0.94), after adjusting for potential confounders. No association between body image and eating and physical activity behaviors was observed among adolescent boys.

Body image may be one of the most important determinants of dietary and physical activity behaviors, and thus future efforts to foster healthy eating and physical activity behaviors among Indonesian adolescents need to address body image concerns.

Despite the rising double burden of malnutrition, adolescent nutrition has received little attention in Indonesia. Eating and physical activity behaviors established in adolescence are known to track into adulthood and may contribute to chronic diseases in later life. This study aimed to explore the eating behaviors and physical activity of Indonesian adolescents, and their influencing factors.

The study, designed as a qualitative study, was conducted in 2 selected districts in Indonesia: Klaten and Lombok Barat. Data were collected through immersion, open and informal discussions, and participant observations with 302 adolescent girls and boys.

The eating and physical activity behaviors of adolescent boys and girls are influenced by contextual changes in their family lifestyles and environment. The adolescents in this study only conflate physical activity with participation in sport. Even when a wider view of physical activity is cast, their level of physical activity remains low, especially for adolescent girls. Adolescents and their families generally eat 3 meals a day, with schools an important source of food for adolescents. Adolescents skip breakfast at home, and breakfast and lunch are usually purchased and eaten at school. Fewer families cook and families rarely eat together due to increasingly busy lives, increased mobility, and digital connectivity.

The rapid contextual shifts taking place in Indonesia influence the home, school, and peer environment to shape eating behaviors and physical activity among adolescent boys and girls. Gender-responsive multicomponent school-based interventions have the potential to serve as an important entry point for influencing adolescent nutrition.
