Dr Sadguna Anasuri – Exploring the Impact of Media Usage on Obesity among Young Adults

Aug 12, 2020 | Health and Medicine, Social Sciences

In the US, the number of children and adults with obesity or excess weight has increased exponentially over the past few decades, causing concerning effects on public health. Identifying factors that may play a role in this rise is of crucial importance, as they could help in devising effective strategies that promote healthier lifestyles. With this in mind, Dr Sadguna Anasuri at Alabama A&M University has carried out research exploring the possible impact of mass media on overweight and obesity in young adults, gathering valuable insights that could inform public health policies.

The Rise of Obesity

Obesity has developed into a significant health concern for many countries worldwide. In the US, the Centre for Disease Control and Prevention has reported a significant rise in the national obese and overweight population over the last few decades. In most US states and territories, over 30% of the population now falls into the obese category.

Excess weight or obesity can significantly increase a person’s risk of developing several health conditions, such as diabetes, high blood pressure, heart disease, arthritis, stroke, fatty liver, renal disease, and certain types of cancer. Therefore, the rise of obesity in the US also means an increase in the prevalence of potentially life-threatening health conditions.

The Government and other national agencies have been trying to devise policies that could reduce the prevalence of obesity by addressing some of its root causes. However, this has proven to be quite challenging and ineffective so far. The recent rise in US obesity rates could result from several different factors, including higher consumption of fatty, salty, starchy, unhealthy foods, combined with an increasingly sedentary lifestyle. Although genetics, family history, certain medical issues, and some medications may lead to weight gain, the primary factor is often physical inactivity.

Dr Sadguna Anasuri has recently researched the impact of mass media on people’s dietary choices and fitness habits. Through her work in this area, she aimed to recommend possible future interventions and policies that could help young people lead healthy lifestyles.

Impact of Mass Media

Although almost everyone now consumes a considerably large amount of media, young adults are spending an increasing amount of time online, using interactive social media sites such as Facebook, Twitter, Instagram, and YouTube. These are focal points where many food businesses, health companies, and fashion industries advertise their products. The advertisements that young adults are exposed to through TV and social media sites can have a significant impact on the products they buy and the habits they acquire.

Dr Anasuri has been conducting extensive research investigating the impact of mass media on the food choices and health and fitness behaviours of young adults. In her recent work, she mainly focused on how exposure to advertising or other forms of marketing on TV and online could play a critical role in the alarming rates of obesity, mainly in the southern state of Alabama.  

Examining Previous Insights

As preparation for her exploratory work, Dr Anasuri reviewed previous research findings and theoretical models that could help in gaining a better understanding of the impact of mass media on the rise of obesity in the US and other countries. In a comprehensive review paper published in 2016, she utilised a conceptual model to illustrate the different factors influencing the dietary and media behaviours of young adults. This model delineates several factors, divided into three categories.

The first category includes personal factors, such as cognitive-affective, biological elements, and individual behavioural patterns about food, eating preferences, and body-image. The second one outlines environmental factors, such as norms of the social or cultural group that the young person belongs to and their social environment (family unit, parenting practices, home environment). Finally, the model also focuses on the role of macrosystems, including political or socio-economic systems at large, food availability, and mass media, and other individual factors such as lifestyle choices and nutritional status.

Dr Anasuri examined these different categories and presented the findings of past research that investigated the impact of various influencing factors on eating behaviours. Her conclusions   showed that the advertising of unhealthy foods on mass media platforms is a major contributing factor to the increase in US obesity rates. The food, beverage, and restaurant industries’ spending on digital media platforms is increasing rapidly – in 2019, it was $1.77 trillion. Also, it has been estimated that 11 out of 12 fast-food companies have Facebook, Twitter, and YouTube accounts.

Other research suggests that young people who watched TV programs containing food advertisements ate 45% more while watching, compared to those who did not. Another study found that children who had a TV in their bedroom were 1.3 times more likely to be overweight than those without one. Strikingly, one study found that the effects of being exposed to specific food advertisements can influence children’s food choices even five years after they first watched an advertisement.

According to research by Strasburger, Jordan, and Donnerstein, one of the reasons why mass media successfully influences children’s behaviour could be their inability to understand persuasive intent and are thus highly influenced by advertising strategies. This highlights the need for parents to supervise their children’s media usage, while also limiting the time they spend exposed to advertising.

Interestingly, Dr Anasuri’s review highlights that many advertisements target youths from a cultural background, such as Latino or African American groups. Past research suggests that since 2003, advertisements for unhealthy foods and sugary beverages targeting African American children have increased significantly, far more than those targeting white children.

An Exploratory Study

One of Dr Anasuri’s studies focused on media use and obesity among young adults between the ages of 18 and 26 years. It examined their exposure to advertising and health-related articles, participation in cooking and health groups, and whether they watched fitness videos available on social media platforms. The overall objective of her study was to identify the role that social media played on young people’s food awareness, choices, and consumption, which could thus partly explain the recent growth in obesity rates.

She surveyed 2000 young adults with a 50-question survey that was administered both online and in printed form. It included questions about media use, perceptions of weight, eating habits, fitness practices, cooking at home versus eating out, online food shopping, family impact, and overall environmental factors that influenced their lifestyle. Dr Anasuri hypothesised that different forms of media – audio-visual, print, and web-based – would impact food consumption among young adults, lead to sedentary lifestyles, and eventually, weight gain. To test her hypothesis, she investigated young adults’ media usage habits on their laptops, smartphones and other devices.

She also gathered a broad range of additional data related to young people’s Internet usage, food and beverage choices, smoking and drinking habits, exposure to online literature on health, food and fitness, involvement in health and fitness groups, and attitudes towards product marketing. In addition to mass media, Dr Anasuri also focused on other social and cultural factors that could impact young people’s consumption of unhealthy foods, causing them to gain excess weight. These factors included education, socio-economic status, family structure, and ethnicity.

Summary of the Findings

Among the demographic differences, gender had some influence on young adults’ perceptions of body weight and their need to lose weight. Females ranked much higher on the frequency of their internet and phone browsing. Females also felt the need to exercise more at home and did more of their shopping online.

The participants’ marital status showed a significant correlation with the frequency of their phone browsing, which included engaging with social media platforms. Surprisingly, income, ethnicity and parents’ education did not seem to have any measurable influence on media consumption and Internet browsing. ‘This shows that regardless of background, being a young adult was the most important factor when it came to media consumption,’ says Dr Anasuri.

She then employed different statistical measures to investigate the significance of such connections. One measure she used was Multiple Factorial Analysis, which revealed that demographic factors mattered the least, food variables followed next, followed by environmental and fitness factors. The highest and most influential factor was their lifestyle, which included the usage of social media platforms, television, and the Internet at large. ‘It was fascinating to note that fitness habits were highly correlated with media use and lifestyle factors,’ says Dr Anasuri.

Potential Interventions

In her paper, Dr Anasuri also outlines some potential interventions aimed at decreasing obesity rates. Among different solutions, the first one involves starting early, by reducing the impact of unhealthy food advertisements on children’s eating habits. This can be done by delivering public service announcements on mass media emphasising the importance of eating healthy, and parent-child communication aimed at teaching children not to be persuaded by advertising. Additionally, policymakers need to place restrictions on the amount of advertising for unhealthy food that is allowed during primetime when most families watch television.

The American Academy of Paediatrics has emphasised the importance of supervising children in their exposure to different forms of media, placing restrictions on the time they are allowed to watch TV or use smartphones and other devices. Some nutrition educators, along similar lines, have introduced initiatives aimed at using social media to increase physical activity through games and sports, and to promote healthier lifestyles and food choices.

Shaping Future Policies

The research carried out by Dr Anasuri provides valuable insights into how advertisements and marketing on mass media platforms could affect the lives of children and young adults. More specifically, it suggests that advertising unhealthy foods or beverages on social media platforms and TV greatly entices young people to buy and consume these products, increasing their chances of gaining weight.

‘More research is needed to better understand how vulnerable teens and young adults are to digital marketing and to explore the health consequences of digital marketing and emerging technologies such as mobile and location-based marketing,’ says Dr Anasuri. Such research could help to determine standards for marketing foods and beverages to children and young adults.

‘Nutritional interventions must help young adults connect with their peers, as they are the source of their identity, self-concept, friendship, independence, and authority,’ continues Dr Anasuri. ‘When supported by their friends, teens are more likely to practice fitness and healthy eating.’

Rather than social media having a negative impact on people’s health and wellbeing, influencing them to eat unhealthy foods, many educators have begun to consider social media as a potential tool for better engaging participants and communicating beneficial information to encourage healthy lifestyles. In the future, Dr Anasuri’s investigations and analyses could be used to develop a set of general guidelines, informing the decisions of policymakers and assisting them in developing more effective strategies to foster healthier lifestyles and eating habits in young generations.

Marine sand is both a vital natural habitat and an essential resource. However, while desert dunes are comparatively easy to observe, their oceanic counterparts are still poorly understood. Dr Xiaochuan Ma and his colleagues at the Chinese Academy of Sciences in Qingdao are mapping the shifting sands of the seafloor and measuring their movement. By investigating how seafloor dunes respond to waves, tides, and typhoons, they can help decision-makers protect and manage this critical resource.

Protecting Palau’s Food Security and Marine Ecology Using Satellite Technology

Palau, a remote group of islands in the Pacific Ocean, relies heavily on wild fish to feed its citizens and support its economy. With a growing population and thriving tourism industry, the country cannot afford a crash in catch size. However, climate change is altering the ecosystems of Palau’s fishing waters, threatening harvests of important fish species. To improve the country’s food security and accelerate the achievement of the UN’s Sustainable Development Goals, the Palauan Government has teamed up with the Nature Conservancy to build a sustainable aquaculture community on the islands, with support from NASA. Using NASA satellite observations, the collaboration helps aquaculture farmers to find optimum locations to farm fish and shellfish, allowing them to produce an abundance of seafood while protecting the surrounding marine environment.

Dr Arpita Bose – Harnessing Microbes to Produce Sustainable Plastics and Biofuels

Before oxygen was widely available in Earth’s atmosphere, ancient microbes looked to other elements to obtain electrons for photosynthesis. Some of these microbes are called ‘photoferroautotrophs’ – which can take up electrons from iron available in their surrounding environment and use them to transform carbon dioxide (CO2) into biomolecules. In their research, Dr Arpita Bose and her team at Washington University in St Louis, explore the mechanisms these microbes exploit to produce biomolecules, using the electrons they take in. Their discoveries are leading to sustainable new ways to produce both plastic and fuel – and could soon prove to reduce our reliance on the compounds derived from crude oil.

Organic materials that can emit light in response to certain stimuli hold great promise for numerous real-world applications. So far, however, their diminished performance on exposure to water has presented numerous challenges. In their research, Dr Jianmei Lu at Soochow University and Dr Quan Li at Southeast University present a new series of compounds that instead display improved light emission when they are transformed into ‘hydrated’ crystals. By assessing the mechanisms responsible for this unique behaviour, the researchers now present new routes towards the widespread use of smart organic materials.
