Childhood lower respiratory tract infections (LRTIs) cause substantial morbidity and under-5 child mortality. The epidemiology of LRTI is changing in low- and middle-income countries with expanding access to conjugate vaccines, yet there are few data on the incidence and risk factors for LRTI in these settings. Methods: A prospective birth cohort enrolled mother-infant pairs in 2 communities near Cape Town, South Africa. Active surveillance for LRTI was performed for the first 2 years of life over 4 respiratory seasons. Comprehensive data collection of risk factors was done through 2 years of life. World Health Organization definitions were used to classify clinical LRTI and chest radiographs. Results: From March 2012 to February 2017, 1143 children were enrolled and followed until 2 years of age. Thirty-two percent of children were exposed to antenatal maternal smoking; 15% were born at low birth weights. Seven hundred ninety-five LRTI events occurred in 429 children by February 2017; incidence of LRTI was 0.51 and 0.25 episodes per child-year in the first and second years of life, respectively. Human immunodeficiency virus (HIV)-exposed, uninfected infants (vs HIV-unexposed infants) were at increased risk of hospitalized LRTI in the first 6 months of life. In regression models, male sex, low birth weight, and maternal smoking were independent risk factors for both ambulatory and hospitalized LRTI; delayed or incomplete vaccination was associated with hospitalized LRTI. Conclusions: LRTI incidence was high in the first year of life, with substantial morbidity. Strategies to ameliorate harmful exposures are needed to reduce LRTI burden in vulnerable populations.

Based on the provided description, here are some potential innovations that can be used to improve access to maternal health:

1. Mobile Health (mHealth) Applications: Develop mobile applications that provide information and resources on maternal health, including prenatal care, nutrition, and vaccination schedules. These apps can be easily accessible to pregnant women and new mothers, providing them with guidance and reminders for important health practices.

2. Telemedicine Services: Implement telemedicine services that allow pregnant women in remote or underserved areas to consult with healthcare professionals remotely. This can help overcome geographical barriers and provide access to prenatal care and medical advice.

3. Community Health Workers: Train and deploy community health workers who can provide education, support, and basic healthcare services to pregnant women and new mothers in their communities. These workers can bridge the gap between healthcare facilities and individuals, ensuring that women receive the necessary care and information.

4. Integrated Maternal Health Clinics: Establish integrated clinics that offer comprehensive maternal health services, including prenatal care, family planning, immunizations, and postnatal care. This approach ensures that women can access multiple services in one location, reducing the need for multiple visits and improving overall care coordination.

5. Public Awareness Campaigns: Launch public awareness campaigns to educate communities about the importance of maternal health and the available services. These campaigns can address cultural barriers, dispel myths, and encourage women to seek timely and appropriate care during pregnancy and childbirth.

6. Maternal Health Vouchers: Introduce voucher programs that provide financial assistance to pregnant women, enabling them to access essential maternal health services. These vouchers can cover costs associated with prenatal care, delivery, and postnatal care, ensuring that financial constraints do not hinder access to quality care.

7. Transport Support: Develop transportation support systems to address the challenge of reaching healthcare facilities in remote areas. This can include initiatives such as community-based transportation services or partnerships with local transportation providers to ensure pregnant women have reliable and affordable means of reaching healthcare facilities.

These innovations aim to improve access to maternal health by addressing various barriers, including geographical, financial, informational, and cultural factors. Implementing these strategies can help reduce maternal morbidity and mortality rates and improve the overall well-being of mothers and their children.
AI Innovations Description
Based on the provided description, the recommendation to improve access to maternal health and reduce the burden of lower respiratory tract infections (LRTIs) in children could be to implement comprehensive maternal and child health programs that focus on the following strategies:

1. Antenatal education and support: Provide pregnant women with information and resources on the risks of maternal smoking and the importance of avoiding it during pregnancy. Offer smoking cessation programs and support to help pregnant women quit smoking.

2. Prenatal care: Strengthen prenatal care services to ensure early identification and management of risk factors such as low birth weight. This can include regular check-ups, nutritional support, and monitoring of fetal growth.

3. Immunization programs: Enhance immunization coverage by ensuring timely and complete vaccination of infants. This can be achieved through improved access to vaccines, education on the importance of vaccination, and addressing any barriers to vaccination.

4. HIV prevention and support: Implement interventions to reduce the risk of HIV transmission from mother to child, such as providing antiretroviral therapy to HIV-positive pregnant women. Additionally, offer support services to HIV-exposed, uninfected infants to reduce their vulnerability to LRTIs.

5. Health promotion and awareness: Conduct community-based health promotion campaigns to raise awareness about the risks of LRTIs in children and the importance of preventive measures. This can include educating caregivers on proper hygiene practices, breastfeeding, and recognizing early signs of respiratory infections.
