Parental Employment Arrangements and Children's Exposure to Ultra- Processed Foods: Evidence from Indonesia
Using 2025 Indonesian survey data, this study reveals that children in dual-earner households face significantly higher exposure to ultra-processed foods compared to those in father-only-employed households, particularly among lower-income families and younger children, underscoring the need for policies that improve access to healthy, convenient foods and regulate marketing rather than relying solely on individual nutrition education.

In many parts of the world, the way families eat is changing. A major shift involves the rise of ultra-processed foods: industrial creations made from refined ingredients and additives, designed to be ready-to-eat, shelf-stable, and intensely tasty. Unlike a home-cooked meal made from raw vegetables or fresh meat, these items are formulated in factories and often come in bright packaging. Scientists have long worried that eating too much of these foods can lead to poor nutrition, but a new question has emerged: how does the daily rhythm of a working family shape what ends up on the dinner table? As more parents work outside the home, families face a constant tension between the need to earn money and the need to feed their children well. When time is tight, the path of least resistance often leads to convenience foods. Understanding whether this pressure pushes families toward ultra-processed options is crucial, because a child's early eating habits can set the stage for their health for decades to come.
Researchers in Indonesia recently set out to investigate this exact dynamic. They wanted to know if the specific arrangement of who works in a household—whether just the father works, or if both parents work—changes the likelihood that children are exposed to a food environment heavy with ultra-processed items. Using data from a massive national survey of nearly 270,000 households, the team looked at children between the ages of one and thirteen. Instead of trying to track every single bite a child took, which is difficult to measure accurately, the researchers examined what the household spent money on. They calculated the share of the family's food budget that went toward items clearly identifiable as ultra-processed, such as packaged cakes, instant noodles, sugary drinks, and processed meats. This spending share served as a window into the food environment the child lived in.
The study uncovered a clear pattern. Children living in households where both parents work are significantly more likely to be in homes where ultra-processed foods make up a large portion of the diet, compared to children in homes where only the father works. The researchers found that when both parents are employed, the probability of a child living in a household with a high share of these foods increases by nearly five percentage points. This suggests that the combined time demands of two working parents create a situation where families rely more heavily on convenient, pre-packaged solutions. Interestingly, the data did not support the idea that a mother working alone is the primary driver of this shift. Households where only the mother worked did not show the same strong link to high ultra-processed food exposure as dual-earner households did. This distinction is important because it points the finger not at maternal employment itself, but at the broader time pressure faced when two adults are working outside the home.
The impact of this work arrangement was not felt equally across all families. The link between dual employment and high exposure to ultra-processed foods was strongest among families with lower incomes, including those classified as poor or vulnerable. For these households, the combination of limited time and limited money makes cheap, shelf-stable, processed foods a practical necessity. In contrast, among wealthier families, the connection between both parents working and high ultra-processed food exposure disappeared. These families likely have the resources to manage their time differently, perhaps by hiring help, buying higher-quality convenience foods, or accessing a wider variety of fresh options, even when both parents are busy. The study also highlighted that younger children, specifically those between one and four years old, are the most vulnerable to these household food environments. Because toddlers depend entirely on what their caregivers provide, the shift toward processed convenience foods in dual-earner homes hits them hardest.
Beyond employment, other factors played a significant role. Families with more children in the house were more likely to rely on ultra-processed foods, likely because these items are cheap, easy to store, and simple to serve to multiple kids at once. Conversely, higher levels of parental education acted as a shield; parents with more schooling were less likely to have households dominated by these foods, suggesting that knowledge and food literacy help families navigate the modern food landscape. The researchers also noted that children in urban areas were less likely to live in high-exposure households than those in rural areas, challenging the assumption that processed foods are only a problem in cities.
The authors are careful to note that their study shows a strong association, not a direct cause-and-effect proof. They cannot say with absolute certainty that working parents cause the shift to processed foods, as other hidden factors like personal food preferences or local store availability could be at play. However, the consistency of the results across different groups of children and families makes a compelling case. The findings suggest that the solution is not to ask parents to stop working, but to recognize that the current food system makes it incredibly difficult for working families to eat well. The study concludes that to protect children's nutrition, policies must go beyond simple advice to parents. Instead, society needs to make healthy, convenient food affordable and accessible, regulate marketing that targets children, and support working families so that nutritious meals are a practical choice, not a luxury.
